In the current research, the efficiency of a hybrid renewable system consisting of a solar parabolic trough collector and the organic Rankine (PTC- ORC) is evaluated. Moreover, the effect of using the photovoltaic module in this coupled system (PTC-PV-ORC) is poked. Due to analyzing the...

Evacuated solar collectors are systems that provide a considerable quantity of heat. However, this system is unable to provide energy in the absence of sunlight. Thus, this study attempts to numerically study a Solar Evacuated Tube Collector (ETC) performance using phase change materials (PCM)....

The effect of the cold wall with different wall distances on ignition at low temperatures is complex and systematic analyses are still needed. Therefore, this work numerically reveals the effect mechanism of wall distance on the spray and ignition characteristics for the diesel engines. In which...

Heavy-duty diesel engines are prone to knocking combustion and even cause piston ablation failures at low temperatures, but the mechanism is not clear. Thus, the above issues are clarified through CONVERGE simulation and transient wall temperature measurement. The results show that local...
