The study aims to develop a novel coil type Pulsating Heat Pipe (PHP) as a heat transfer enhancement devise for heat exchangers. PHP is an efficient passive heat transfer device with high effective thermal conductivity, suitable for applications like electronic cooling, waste heat recovery, and solar heat transfer. The current passive methods in heat exchangers have limitations in enhancing heat transfer, and new passive techniques are needed to increase heat transfer. PHP can be used to enhance heat transfer coefficient in the annular region of double pipe heat exchangers by increasing turbulence and acting as high thermal conductivity fins. The study will investigate the thermal performance of this coil type PHP, conduct experimental and numerical studies for closed end and closed loop PHP, and apply it to an air-water double pipe heat exchanger.
