Abstract

Pulse Jet impingement heat transfer can be used for various applications which requires high convective heat transfer coefficient. The aim of this study is to develop multiple pulsating jet mechanism using a rotating valve pulse jet system. Pulsation of the air jet was produced by a rotating cylinder valve mechanism at frequencies between 10-80 Hz. Multiple pulsating jet mechanism has been developed based on the results of velocity and temperature profile obtained from the single nozzle pulse jet mechanism. Earlier results of the flow structures for a single nozzle pulsating jet mechanism plotted show a distinctive exit air jet profile which can affect the multiple pulsating jet impingement heat transfer characteristics. Dual nozzle pulsating jets have been considered for the new design and the distance between the nozzle and the phase angle are the main parameters that will affect the rate of heat transfer. More nozzles can be added to the system based on the needs of application. A new experimental set-up will be built based on the developed multiple pulsating jet mechanism in order to study the effect of these two main parameters on the cross flow interactions and turbulence intensity of the pulsating jets.
