Because of the rapid development of the economy and the process of urbanization, construction waste recycling is becoming increasingly important and should be considered. Motivated by effectively managing the construction waste recycling under sustainability incentives, the multi-agent stochastic game model is used to evaluate the evolutionary behavior of the government agencies, waste recyclers, and waste producers. To capture the uncertainty existing in the external environment, the replicator dynamic formula is integrated with Gaussian noise, and the Lyapunov exponent diagram is analyzed to illustrate the nonlinear dynamic behavior. The numerical approximations are then solved by utilizing the random Taylor expansion formula. Finally, a numerical simulation is performed to evaluate the evolutionary trajectories of the participants involved. The findings revealed that: (1) the government agency should adopt a positive supervision approach, which can encourage waste producers and recyclers to collaborate around each other; (2) lower sorting and disposal costs can enhance construction waste recycling; and (3) the existence of uncertainty in the environment around different participants will influence one’s strategy selection.

Harvested from ORCID Public Data FileZhaolin Gu in OpenAIREAbstractIndoor environmental control has been proved to be critical for long-term preservation for artifacts in archaeology museums. However, it is usually a very energy intensive process to sustain a steady condition continuously throughout the year for the whole exhibition hall. In this study, an energy efficient strategy that only controls the local environment for the preservation area is proposed. A laboratory room with a funerary pit was constructed to simulate a large open exhibition hall. Experimental investigations using the test pit, with radiant panels and air curtain system for control of the local environment for the funerary pit, validated this management strategy for the preservation of relics in archaeology museums. The results show that using both an air curtain and a radiant heating system provides a feasible and energy-saving strategy for controlling the preservation environment independently.

Harvested from ORCID Public Data FileZhaolin Gu in OpenAIREIn this study, we explain the causes and effects of the geometrical impossible result encountered in the widely adopted tetrakaidecahedron model (Boomsma and Poulikakos, 2001; Dai et al., 2010) for the effective thermal conductivities (ETCs) of metal foam. The geometrical impossible result is successfully eliminated by accounting for the size variation of the node with porosity. The improved model provides predictions of ETCs that are more precise than available models. For aluminum foams (ks=218Wm-1K-1) using water and air as fluid media, the relative root-mean-square (RMS) deviation of the present predictions from the experimental data is about 5.3%; for the reticulated vitreous carbon (RVC) foams (ks=8.5Wm-1K-1), the relative RMS deviation is about 7.4%.

Harvested from ORCID Public Data FileZhaolin Gu in OpenAIREAbstract This study presented an experimental investigation on heat transfer performance of a shell-and-tube heat exchanger with and without circular fins. Particular attention has been paid to the effect of injection flow rate of heat transfer fluid (HTF) on the thermal performance of the heat exchanger. A purposely-designed apparatus was built for experimental observation. Results showed that the application of fins had a great effect on improving phase change heat transfer and the full charging time was significantly reduced. Injection flow rate of HTF was found to have little influence upon the performance of the heat exchanger.

Harvested from ORCID Public Data FileZhaolin Gu in OpenAIREFor coal tar hydrocracking process in supercritical gasoline, it requires a new catalyst with high activity under low temperature conditions to improve the light oil yield. The effects of Mo–Co–Y and Mo–Ni–Y series catalyst on the light oil yield were investigated in this paper, and the coke deposition on catalyst and catalyst stability were also investigated. Experimental results show that the Mo–Co–Pd–Y zeolite catalyst with a suitable Co/(Co+Mo) atom ratio and calcination temperature could maximize the light oil yield, and the acid amount of the catalyst is closely related to its activity. Coke deposition on the Mo–Co–Pd–Y zeolite catalyst is very little and the catalyst remains high activity within used time of 8 h.

Harvested from ORCID Public Data FileZhaolin Gu in OpenAIREAbstract Due to sustainable development, solar energy has drawn much attention and been widely applied in buildings. However, the application of solar energy is limited because of its instability, intermittency and low energy density in winter. In order to use low density and instable solar energy source for heating and improve the utilization efficiency of solar energy, a solar phase change thermal storage (SPCTS) heating system using a radiant-capillary-terminal (RCT) to effectively match the low temperature hot water, a phase change thermal storage (PCTS) to store and continuously utilize the solar energy, and an air source heat pump (ASHP) as an alternate energy, was proposed and set up in this research. Series of experiments were conducted to obtain the relation between the solar radiation utilization rate and the heating supply temperatures, and to evaluate the performance of the RCT module and the indoor thermal environment of the system for its practical application in a residential building in the north-western City of Xi’an, China. The results show that energy saving of the solar heating system can be significantly improved by reducing the supplied water temperature, and the supplied water temperature of the RCT would be no more than 35 °C. The capillary radiation heating can adopt a lower water temperature and create a good thermal comfort environment as well. These results may lead to the development of designing and distributing the solar energy for building heating during winter.

Harvested from ORCID Public Data FileZhaolin Gu in OpenAIREAbstract Indoor environmental controls are critical considerations when preserving artifacts in museums. Controlling the indoor environment of site museum buildings with large space layout typically consumes large amounts of energy. Most of the energy load needed to preserve relics is dissipated throughout the non-occupied space, because the environments that contain the relics occupy relatively little space compared to the entire exhibition hall. In this study, an energy efficient local ventilation system was proposed to independently control the environment of a funerary pit, which was preserved within a museum separate from the large exhibition hall. An experimental hall, which consists of a funerary pit and an experimental local ventilation system, was built to simulate a site museum building. Experiments were conducted to investigate the system’s performance and to validate its ability to preserve historical terracotta figurines in their semi-exposed pits within the exhibition hall. The study evaluated the stability of the conservation environment and the system’s energy usage by assessing the effects of the ventilation rate. The experimental results showed that the local ventilation system provides an energy-saving strategy supporting the environmental control of the funerary pit. The LV system significantly decreased temperature fluctuations in the funerary pit and temperature differences across semi-exposed relics. The system could be used to control the local preservation environment of the funerary pit separately from a large space exhibition hall.

Harvested from ORCID Public Data FileZhaolin Gu in OpenAIREWind corridors are expected to be effective in alleviating the canopy urban heat island effect and air pollution. However, investigations on airflow characteristics within wind corridors, especially the influences of structural factors, are still limited. This current work performed numerical simulations on a group of idealised wind corridor models with different aspect ratios (ARs) and varying heights and/or widths along the corridors. Simulations revealed that the AR value had a vital influence on the wind speed, and an AR value of 0.1 facilitated the best ventilation conditions within the wind corridor. Structural variations along the corridor have a critical influence on ventilation, where the width contraction (contraction structure) and high-rise buildings (protrusion structure) would considerably weaken the wind speed within the corridors. The results suggested that wider and step-up structural design along the corridor should be encouraged in urban wind corridor planning, which would be helpful in promoting ventilation efficiency; but contraction structures should be prevented for primary wind corridor design.
