Abstract:
There are various methods for increasing heat transfer rates between a fluid jet (or array of jets) and an impingement surface. In a current investigation of pulsed flow impingement heat transfer, a pulsed jet with variable duty cycle impinging upon a heat transfer surface is capable of enhancing heat transfer relative to the heat transfer rate for steady flows. This principle is the subject of an in-depth experimental study. In the future this work will be extended to include numerical simulations. Potential applications include electronics cooling and drying processes in the manufacturing industry. Initial results indicate more than 50% heat transfer enhancement associated with control of the duty cycle parameter with a mechanical valve for use in industrial systems which is currently under development. Further experiments into boundary layer instability, and high frequency pulsations are under way.
