Abstract

Numerical analysis of passive two phase fluid flow in a 3D Closed Loop Pulsating Heat Pipe (CLPHP) with turns in evaporator and condenser section is carried out. Water is used as working fluid. The volume of fluid model (VOF) is used to simulate passive two-phase fluid flow in a Closed Loop Pulsating Heat Pipe. Filling ratio (FR) of is kept in the range of 60 to 70%. The evaporator temperature is set in the range of 353 K. The condenser temperature is set in the range of 298 K. The contours of volume fraction water, wall temperature and contours of mass flow rate is studied. Analysis of fluid flow is done with various geometrical parameter for 3D Closed Loop Pulsating Heat Pipe. Alternative liquid and vapor slug formation are observed and evaporation and condensation process are visualized in the analysis.
