Study of Heat Transfer Enhancement by Pulsating Flow in a Rectangular Mini Channel

Pulsating flow is viewed as a promising mechanism for augmenting heat transfer in single-phase cooling systems and could help to better regulate temperatures in applications involving high heat flux densities and/or those applications where fluid flow is restricted to confined spaces. Although the phenomenon is commonly observed in biological processes such as arterial blood flow, pulsating flow may be particularly suited to areas such as electronics cooling and performance enhancement of heat exchangers. Due to the complexity of the coupled pulsating fluid flow and heat transfer and the wide range of pulsation formats that could be employed, a comprehensive parametric analysis of the phenomenon is considered to be of great interest.
