Numerical Study on Enhanced Paraffin/Air Heat Transfer with Extended Surface

摘要：

　　The extended surface is used to enhance paraffin/air heat transfer because of the paraffins poor thermal conductivity,and the heat storing and releasing capacity of paraffin heat storage layer with variety of extended surface are compared by numerical simulation.The results show that:the heat storage layer with vertical rectangular fin extended surface has stronger ability on the heat storage and release,and can more effectively improve the air flow velocity in the solar chimney power plant system with vertical heat collector.Due to the restrictions of manufacturing,the heat storage and release capacity is stronger when the heat storage layer surface area with vertical rectangular fin is from 3.4 times to 5.8 times compare to the flat-plate heat storage layer.
