ABSTRACT A detailed overview of heat pipes is presented in this paper, including a
historical perspective, principles of operations, types of heat pipes, heat pipe performance …

The world is running against time to develop enough source of sustainable energy.
Producing a viable and eco-friendly energy source is one part of the solving the energy …

Over the last several decades, several factors have contributed to a major transformation in
heat pipe science and technology applications. The first major contribution was the …

Pulsating (or oscillating) heat pipes (PHP or OHP) are new two-phase heat transfer devices
that rely on the oscillatory flow of liquid slug and vapor plug in a long miniature tube bent …

Analytical models for both unlooped and looped Pulsating Heat Pipes (PHPs) with multiple
liquid slugs and vapor plugs are presented in this study. The governing equations are …

Pulsating heat pipes have received growing attention from experimental and theoretical
researchers in recent times. Behind its constructional simplicity lie the intriguingly complex …

Heat transfer in the evaporator and condenser sections of a pulsating heat pipe (PHP) with
open end is modeled by analyzing thin film evaporation and condensation. The heat transfer …

We provide the high speed flow visualization results for the closed loop pulsating heat pipes
(PHPs). It is identified that there exists the bulk circulation flow which lasts longer and the …

The control theory (system identification theory) is introduced to quantitatively analyze the
start-up performance of the closed-loop pulsating heat pipes (CLPHPs) based on an …

This article discusses a focused study on visualizing the flow patterns in a two-phase
pulsating heat pipe (PHP) using Fe3O4/water as the working fluid at 3 V/V% concentration …
