Flow and heat transfer of fluid in a pulsating heat pipe

Cooling of electronic components are preferred heat pipes imbedded in heat sink because of high heat transfer through them. The oscillating motion of the working fluid due to continual phase change facilitates both sensible and latent heat transfer in pulsating heat pipes. This enables transfer of high heat flux efficiently over long distances. In this work, a mathematical model is developed to optimize the parameters which involves in heat pipe design. The parameters are filling ratio, size of tubes and degree of temperature. In House Finite Volume based CFD solver is used for simulation. The obtained simulation results are validated against experimental results present in literature. These results are useful for understanding thermos-hydrodynamics of pulsating heat pipe for achieving maximum thermal performance (paper)
