Abstract In this paper, discussing in detail on how the thermal efficiency of the cooking stove fuelled by firewood can be increased to achieve maximum efficiency. For this purpose, a biomass stove is fabricated and tested domestically for regular household chores. Unlike regular biomass stoves, a number of design optimizations were made while fabrication to achieve the end goal. Biomass energizes are still being used by large number of populations in remote areas around the globe where the access to LPG gas stoves is limited because of location proximity and economy. Its simplistic design makes it unsuitable to perform any controlled test because they are known to display lots of variability in their performance. So, the other objective of this paper is to comprehend and characterize range of process involved inside the biomass stove and put forth a thorough analysis on all the variables to better configure for future use.

The Metal matrix composite materials is particularly are widely used in automotive engineering applications. In this work discuss with production of Al/SiC composite and investigate it's suitability for the application on Connecting Rod. The results were compared with conventional material C70 Steel. The connecting rod is manufactured using the stir casting method. The basic properties were obtained by mechanical testing. The test results were used for FEA. The connecting rod is designed and meshed using solid works and hyper mesh, and then analysis is done used by ANSYS work bench 14.0 software. The results show that the composite connecting rod is more efficient than the conventional ones.

Fuel price fluctuations and environmental degradation have developed interest in the area of biodiesel. In the present study, we investigated the performance and pollutant features of a DI diesel e...

Abstract The industries like power plant, automobile etc. demanded the heat transfer enhancement for heating, cooling and evaporation applications through the equipments like air conditioning, radiators, refrigerators etc. There are passive and active or combinations of them are employed based on the requirement. As the passive technique is uncomplicated, it preferred widely for enhancing the heat transfer in pipes of the heat exchanger. The increase of thermal conductivity of fluid medium by means of nano fluid and the flow resistance offered by inserting the by inserting the twisted tape with rectangular cut on its rib. The titanium dioxide, Beryllium oxide or beryllia, zinc oxide and copper oxide nanofluids with base fluid of plain water. The numerical study is investigating the thermal performance with respect to the laminar to turbulence flow with various nanofluids in the heat exchanger pipe with insert of twisted tape with rectangular cut on its rib. The results are compared and best nanofluid was suggested.

The demand in fuel needs and the depleting fossil fuels raised the need towards bio-fuels. The emerging trend in research field is highly focused on biodiesel production and their characteristic analysis. Since pollution is a major threat to the environment, emission parameter analyses are much important to be concentrated. As the entire world contains plenty of biofuels, it is necessary to explore them for its efficiency and analyze their parameters. In this experimental work jatropha and cashew nut shell biodiesel (Cardanol) was extracted and they were blended with diesel. The characteristics of jatropha and cardanol biodiesel were studied in the DI diesel engine by varying the load at the same speed. In brief, this experimental analysis is carried out to compare the emission characteristics between Jatropha biodiesel at 20% (B20) and 40% (B40) and Cardanol biodiesel blends at 20% (C20) and 40% (C40).

Abstract Because of increasing automobiles, power plants and factories, increasing of this automobiles, power plants produce the more emissions like CO, HC and NOx. So that the world is searching for the alternative fuel, which will not create any harm to the environment and also it would be less in cost. Biodiesel is one of the main solutions to the global energy crisis. In this present work studied the performances and emission characteristics of Tamarind Seed Oil Bio-diesel (TSO). Use of additives for better combustion characteristics to the biodiesel. The blends of Tamarind Seed oil (TSO) with the additives Aluminum oxide (Al2O3) are B10 + 20 PPM Al2O3, B20 + 20PPM Al2O3, B30 + 20 PPM Al2O3. This blends were analyzed and their performance and emissions characteristics compared with performance and emission characteristics of diesel. Tests were carried out over entire range of engine operation at varying conditions of load. The engine exhaust gas emissions are reduced with increase biodiesel concentration.

The main fuel for transport is diesel. It adds to the success of overall economy, as it is widely used due to its high efficiency in combustion, versatility, unwavering quality and cost-effectivene...
