Plenum pressure behavior in transiently heat loaded transpiration cooling system

Abstract:

In this paper, the behavior of the plenum pressure behind a transpiration-cooled porous material sample after an incident surface heat flux to the sample is analyzed in experiment and theory. Two porous materials, zirconium diboride and carbon/carbon, were characterized using the pressure-based noninteger system identification method. The resulting impulse responses are analyzed based on two numerical models. One model calculates a plenum pressure impulse response by modeling the porous sampl...
