Effects of impingement gap and hole arrangement on overall cooling effectiveness for impingement/effusion cooling

International Journal of Heat and Mass Transfer, 2020
Abstract The effects of geometrical parameters on overall cooling effectiveness were experimentally investigated on the flat plate with impingement/effusion cooling. Geometrical parameters investigated included two relative positions of impingement and effusion holes (staggered arrangement and overlapped arrangement) and three impingement gap ...

System-Level Impingement Cooling with Cryogens

Journal of Thermophysics and Heat Transfer, 2020
System-level impingement cooling with cryogens has potential thermal applications in size-constrained, weight-constrained, and power-constrained or low-atmosphere environments by utilizing a phase change for enhanced heat transfer at cryogenic temperatures. In this work, an experiment capable of measuring the heat and mass flow of liquid nitrogen jets
