    Abstract In a trial, 10 cucumber plants ( Cucumis sativus , variety ‘Virgo’ F 1 hybrids) were exposed continuously to a concentration of negative air ions exceeding 50 000/c.c. for a period of 40 days. The yield and productivity of the treated plants were compared with those of a control group of 10 plants in a matched-pairs experiment. An Index of Initial Vigour was developed to allow the subsequent production of the previously nursery-grown young plants to be related to their condition at the beginning of the trial. No effect on the total production or productivity at the end of the 40-day period was discerned, but the interim results (e.g. for the 10th day) are consistent with a model of reaction to stress governed by a negative-feedback mechanism. No harmful effects of the use of negatively ionised air were detected.

    Abstract The almost two-dimensional steady-state rates of heat loss from arrays of uniformly-spaced vertical rectangular fins, extending upwards—in otherwise stagnant air—from horizontal heated bases, have been measured. (The vertical air gaps between the fins were closed at their sides, by insulated vertical end-barriers.) The effects of various combinations of height, thickness and spacing of the fins, for different base temperatures (in the range 40 to 100°C), have been studied. For the configuration considered, in a normal ambient environment (∼ 20°C), there is an optimal fin spacing (⋍ 16 mm) corresponding to the greatest steady-state rate of free convective/conductive heat loss through the air from the finned system, and this is almost independent of the temperature of the heat exchanger base (in the range 40–100°C). At this optimal spacing for base temperatures not greater than 50°C, the convective/conductive heat transfer rate from the array increases with the fin height up to about 60 mm, so that it would be uneconomic to employ taller fins if convection/conduction is dominant compared with radiation. If the radiation contribution is also considered, then the optimal spacing corresponding to the maximum total steady-state rate of heat loss through the air is somewhat less than the optimal spacing for which, under the same temperature conditions, the maximum steady-state rate of convective/conductive heat leak occurs. The greater the emissivity of the heat exchanger surfaces, the narrower the optimal uniform gaps between the fins. A two-dimensional finite-difference computer program has been composed to predict the temperature distribution throughout the heat exchanger for a stipulated ambient environmental temperature and experimentally-determined distribution of the heat transfer coefficient over the surfaces of the exchanger. This enables, for instance, any hot spots to be located prior to a proposed design being built.

    Abstract Temperature is one of the factors which affect the power availability, driveability and durability of the battery pack. Folded fin and serpentine channel are commonly used to provide cooling for the battery pack. During the cooling process, fluid absorbed the heat generated along the flow direction and caused the reduction of the cooling capacity. Hence, downstream temperature is always higher than the upstream temperature. Inconsistent cooling effect will lead to high variation of temperature distribution and shorten the life expectancy of the battery pack. In this study, a battery module consists of three pieces of LiFePO4 pouch cell arranged side by side, and aluminium foam is sandwiched between two heat spreaders to form a cooling plate. Aluminium foams with different porosity and pores density were modelled to investigate the thermal performance and flow field numerically. Correlation of Nusselt number, permeability and resistance loss coefficient from the literature was extracted and used in the CFD simulation. From the simulation results, it is shown that 10 PPI aluminium foam with 0.918 porosity offered the highest thermal performance and lowest flow resistance. Hence, the optimized aluminium foam cooling plate can be used as a new type of cooling system for the battery pack.

    This paper describes the nexus of energy justice, supply and security. It advances the case that energy justice is the relatively new concept in this triangle of issues and an area requiring research. There are three central tenets of energy justice: distributional, procedural and recognition justice. Each of these tenets figures at certain stages in the energy supply chain and as a consequence there is an effect on energy supply. An example of the wind energy sector in Denmark is presented which demonstrates how the application and promotion of energy justice can enable the growth of an industry supply chain. This in turn contributes to increased energy security and national economic growth.

    Abstract An experimental investigation of the steady-state rates of heat transfer from an array of vertical rectangular fins of 3 mm thickness and 250 mm length, protruding 60 mm perpendicularly upwards from a 250 mm × 190 mm horizontal rectangular base, is reported. For constant (to ±0·1°C) base temperatures between 40°C and 80°C, in an ambient environment of 20±0·2°C, the optimal separation of the parallel fins, corresponding to the maximum rate of heat loss, is 10·5±1·0 mm. The effects of the extent of the fin protrusions on the thermal performances of such vertical fins, on the same base, which was arranged to be either vertical or horizontal , have been studied. The experiments were performed with three different fin protrusions, namely 32 mm, 60 mm and 90 mm, for a base temperature of 40°C above that of the ambient environment. The steady-state rate of heat dissipation from the fin array increased slightly less than linearly with the fin protrusion for both orientations, but the relationship became closer to linear as the fin spacing was increased. A comparison of the abilities to dissipate heat to the room air from the same geometrical configuration having a rectangular fin array but positioned with vertical fins on a vertical base, vertical fins protruding upwards from a horizontal base, or horizontal fins on a vertical base, has been made. The orientation with vertical fins protruding upwards from the horizontal base, is the preferred option because of the relatively high rates of heat transfer that can then be achieved.

    The purpose of this paper is to provide a broad overview of the social and environmental costs and benefits of biofuels in Asia. The major factors that will determine the impacts of biofuels are: (1) their contribution to land-use change, (2) the feedstocks used, and (3) issues of technology and scale. Biofuels offer economic benefits, and in the right circumstances can reduce emissions and make a small contribution to energy security. Feedstocks that involve the conversion of agricultural land will affect food security and cause indirect land-use change, while those that replace forests, wetlands or natural grasslands will increase emissions and damage biodiversity. Biofuels from cellulose, algae or waste will avoid some of these problems, but come with their own set of uncertainties and risks. In order to ensure net societal benefits of biofuel production, governments, researchers, and companies will need to work together to carry out comprehensive assessments, map suitable and unsuitable areas, and define and apply standards relevant to the different circumstances of each country. The greatest benefits may come from feedstocks produced on a modest scale as co-products of smart technologies developed for phytoremediation, waste disposal and emissions reduction.

    Abstract Global energy consumption is increasing at a dramatic rate and will likely continue to do so. The major source of energy is still fossil fuel, which has resulted in the well-documented problem of global warming due to the emission of greenhouse gases from the burning of such fuel. Climate change and global warming are among the crucial and complex issues encountered by the world today, and they require an immediate solution. Technological innovation is the key to ensuring energy security without causing emissions and providing efficient cost-effective energy solutions. Power electronic technologies offer high reliability and renewable energy conversion efficiency, thus contributing to energy conservation, improving energy efficiency, and helping in the mitigation of harmful global emissions. This review focuses on various aspects of power electronic technologies and their importance in tackling carbon emission and global warming problems. The key topologies of power electronic converters are explained based on types, control difficulties, benefits, and drawbacks. Power electronic controllers utilized for energy conversion are comprehensively reviewed with regard to their structure, algorithm complexity, strengths and weaknesses, and mathematical modeling. The review focuses on power converters and controllers used in different applications and highlight their contributions to energy conservation, increasing the share of renewable energy sources, and mitigating emissions. Moreover, existing research gaps, issues, and challenges are identified. The insights provided by are expected to lead to the enhanced development of advanced power electronic converters and controllers for sustainable energy conversion. Such development can reduce carbon emissions and mitigate global warming.

    Abstract A coalfield, in excess of 120×10 6 tonnes of coal in situ , has been discovered at Al-Kamil in south-eastern Oman. The coal is classified as highly-volatile bituminous type-A, with an average calorific value of 27.5 GJ per tonne. Unfortunately, it has on average ∼5% by weight sulphur content and an ash content of ∼14% by weight: so it is probably better suited for use as a fuel for electricity generation. However, such coal-fired generation, at present, would incur a higher cost than using indigenous natural gas, but would nevertheless provide an opportunity for diversification away from the existing over-dependence on natural gas and crude oil.

    Abstract Steady-state convective heat-transfer and pressure-drop characteristics for laminar air-flows over a horizontally-orientated simulated printed-circuit board (PCB) assembly have been measured experimentally and predicted numerically. The considered assembly consisted of a plate with uniformly-spaced identical electrically-heated rectangular uniform ribs mounted orthogonal to the mean air-flow. Mathematical correlations were determined between the cavity-height to ribs' protrusion and width-to-protrusion ratios, namely ( H B ) and ( L B ), respectively, and the Reynolds number (Rec) of the air-flow with the steady-state Nusselt number (Nuc) and friction factor (fc), both of these latter parameters being highly dependent on H B . When H B ≥8 , natural convection provided a significant portion of the total rate of heat transfer, and mixed (i.e. forced plus natural) convection ensued. For assemblies with ribs each of the same volume, the assembly with the ribs having a larger top surface-area has the higher heat-transfer coefficient and smaller pressure drop under otherwise identical conditions.
