A Numerical Investigation Of The Signicance Of Non-Dimensional Numbers On The Oscillating Flow Characteristics Of A Closed Loop Pulsating Heat Pipe

Authors: Ch Sreenivasa Rao, AVSSKS Guptay, K Ramanarasimhaz

Pulsating Heat Pipe (PHP) is a two phase passive heat transfer device for low temperature applications. Even though it is a simple, exible and cheap structure, its complex physics has not been fully understood and requires a robust, validated simulation tool. In the present work the basic theoretical model by H.B. Ma et al[11] has been updated with the inclusion of capillary forces in order to characterise the pulsating ow under the in uence of various non dimensional quantities. The mathematical model is solved using explicit embedded Range-kutta method and proved that the Poiseuille number considered in the numerical analysis assumes more signicance since it includes ow characteristics, geometry and uid properties of a PHP.
