Abstract

Impingement cooling is an effective method for removing heat from a high temperature target surface using sprayed jets oriented to impinge on the surface. Detailed local heat-/mass-transfer distributions are measured using the naphthalene sublimation method. The main parameters of this study are jet hole spacing ( $s/d = 4$ , 8) and crossflow rate. The heat-/mass-transfer coefficients on the target surface are significantly influenced by the crossflow volume and pin-fin structures, and the degree of this influence is affected by different jet hole spacings. The results indicate that a small hole spacing increases the heat/mass transfer by 15%-30% than a large hole spacing for the Reynolds number of 15 000.
