Pulsating Heat Pipe

A pulsating heat pipe (PHP) is a promising two-phase passive thermal device that consists of a capillary tube meandering between an evaporator (heating section) and a condenser (cooling section). The PHP is partially filled with a working fluid that exists as a mixture of liquid slugs and vapor plugs. 

Heat is transferred from the evaporator to the condenser by the self-excited oscillation of vapors and liquids. Compared with other two-phase passive thermal devices, such as conventional heat pipes and loop heat pipes , PHPs have many advantages, including having a simple construction, being lightweight and flexible, and having no internal wick structure because PHPs consist of meandering capillary tubes. Low-cost, commercially available tubes can be used for PHPs without special processing. Consequently, the manufacturing costs of PHPs are lower than those of other two-phase thermal devices.

Project Collaboration

This project is jointly conducted by Prof. Kamlesh Parmar and Nirmal Parmar. Prof. Kamlesh Parmar is responsible for conducting the experiments on PHP. Whereas Nirmal Parmar is mainly working on preparing data-driven solutions (Machine Learning)  for PHP.
