Scope of CFD analysis in Closed loop pulsating heat pipe (Review Paper)
A heat pipe is device used to transfer Heat from hot surface to cold surface. It combines the principles of both thermal conductivity and phase changes to efficiently manage the transfer of heat between two solid surfaces. Heat Pipes are of two types. 1) Open loop pulsating Heat pipe 2) Closed loop pulsating Heat pipe. Closed loop Pulsating Heat pipe gives better results. The performance of CLPHP greatly depends on filling ratio, working fluid, internal diameter, inclination, pipe material etc. Although a lot of research have been done improvement can be done in the performance.A lot of research papers & literatures are reviewed.The Research Papers of Sameer khandekar, Piynun Charoenswan , Ya ling He, Xiangdong, Hua Han are studied . Working fluid generally taken as water + Ethanol filling ratio taken as 30%-50 %. In most of the cases filling ratio is taken as low upto 50% & pipe arrangement is also almost horizontal. But there are a lot of possibilities of improvement in Heat Transfer by changing pipe material, increasing filling ratio up to 80 % & by taking working fluid as R134 or R22.CFD Analysis can be done for creating model of heat pipe & different conditions can be applied for comparative study.
