Abstract
Verification of a computational fluid dynamics model to predict the fluid flow & heat transfer of pulsating impinging jets.Quantification of the stagnation and area-averaged heat transfer enhancements achieved by flow pulsation.The effect of Reynolds number, jet-to-surface distance, nozzle diameter, pulsation frequency on heat transfer enhancement.Proving an insight into the near-wall behaviour in the viscous sublayer to realize the governing heat transfer mechanisms.
