The structure and inclination angle of a pulsating heat pipe are critical factors influencing the transfer performance operation mode. In this work, single-layer double-row is designed, start-up characteristics at limit angles (0?, 90?, 180?) experimentally investigated. Also, mode studied through infrared imager temperature profiles. study highlighted that has excellent in angle. When 0?, impr...

The aim of the article is to numerically model a two-dimensional multiphase flow based on volume fluid method (VOF) in pulsating heat pipe (PHP). current state knowledge regarding modeling these devices was studied and summarised. proposed developed within open source software, OpenFOAM, predefined solver called interPhaseChangeFoam. analyses were carried out terms influence four different mass...

Proton exchange membrane fuel cell (PEMFC) has the advantages of high energy efficiency, clean, pollution-free, fast start-up and noise-free, but its thermal management problems still restrict development practical application PEMFC. This paper analyzes important influence heat on working performance proton cell, summarizes structure principle effect evaluation system using pipe under premise s...

This paper presents the experimental investigations conducted on a vertical closed loop pulsating heat pipe (VCLPHP) to evaluate the thermal performance. The values of thermal resistance and heat transfer coefficient obtained in the experimentation is used as evaluation parameters. The VCLPHP used has capillary tubes having an inner diameter of 2mm and outside diameter 3mm and bent into 5 turns...
