PSP Measurement of the Jet Impingement Flow Field over a Flat Plate

Abstract

The pressure sensitive paint (PSP) has recently received wide attention as a revolutionary new optical pressure measurement scheme. The objective of the present work is to show the feasibility of PSP as a measurement tool of jet impingement flow fields. The results show that the large difference of the wall static temperature leads to nonphysical results. The key points necessary for the reliable measurements is thermal diffusively to keep uniform wall temperature.
