Numerical Optimisation of Heat Transfer using Combined Steady and Pulsating Jet Array
Journal Title: GRD Journal for Engineering - Year 2017, Vol 2, Issue 6
Abstract
Cooling of heated plates finds applications in various fields like cooling of electronic devices. Commonly used method for cooling of electronic devices such as computers is by using fan. With the advent of electronic industry cooling requirements from compact surfaces become the primary focus of research. Jet impingement cooling mechanism with pulsating impinging jet array has proved to be one of the most efficient heat transfer mechanism for cooling applications. The idea of impingement heat transfer is to obtain the higher heat transfer coefficients from a given surface with limited area by means of the high velocity of the jets. Thus, a study is required to optimize the different aspects of the mechanism so as to achieve maximum heat transfer. In this project combined steady and pulsating jet array is used for heat transfer. Various arrangements of jets are considered. Also analysis of different frequencies of jets is done. The best combination for maximum and uniform heat transfer is to be found out. The study is being conducted with the help of CFD simulation package Ansys Fluent.
