Augmented heat transfer in a pin fin channel with short or long ejection holes Academic Article uri icon

abstract

  • Experiments are performed to determine the heat transfer, pressure drop, and mass flow rate in a pin fin channel with short or long ejection holes on one of the channel sidewalls. The test section consists of eight copper segments that are individually heated to maintain an isothermal boundary wall condition. The segmentally averaged Nusselt numbers are determined. The heat transfer in the pin fin channel with sidewall ejection flow is about 25-30% lower than that with the straight flow. The length of the sidewall ejection holes does not significantly alter the heat transfer in the pin fin channel for the lengths of the ejection holes considered. © 1991.
