Pulsating heat pipe are passive heat transfer device where heat transfer is higher as compared to the common heat transfer devices such as metal fins and Heat pipe. The main reason for this is the two-phase phenomenon occurinside PHPs with the oscillatory motion of the bubbles. The flow in pipe is Multi –phase flow, vapor plugs and liquid slugs are created in PHP due to the capillary action. In this work, CFD analysis on a two turn CLPHP in ANSYS FLUENT 15.2 with overall size of device being 60mmx 173mm, diameter 2mm and distance between the tubes as 20mm.The tubes were made of copper, 50% of the volume filled with water (working fluid).This project mostly focus on thermal resistance analysis of CLPHP at various orientation such as vertical, inclined 45˚ and horizontal.
