On Studying Fluidic Motions in an Oscillating Heat Pipe

Abstract:

This study develops an analytical model applicable for predicting the fluidic motion of an oscillating heat pipe (OHP) with asymmetric arrayed channel configuration. The analytic model considers the temperature difference between the average evaporating region and the average condensing region as the thermally driven force for the fluidic motion. The calculated results show that the closed-loop OHP with asymmetric arrayed channel under lower number of turns, lower filled liquid ratio, higher operating temperature and higher temperature difference between the average evaporating region and the average condensing region for the frequency ratio of unity could attain a better performance of the fluidic motions.
