Global Estimation of Heat Transfer in Spray Cooling Using Inverse Heat Conduction
Madhu Ganesa-Pillai and A. Haji-Sheikh

Spray impingement cooling using a two-phase, two-component mixture is an efficient method of removing high heat flux. The serious study of spray cooling phenomena requires an accurate knowledge of the heat flux and temperature at the impingement surface. In this paper, the estimation of heat flux at the surface during spray cooling using the inverse heat conduction method is discussed. The solution of the inverse heat conduction problem using the Green’s function solution equation is derived in detail. The effect of data noise on the solutions is studied. The input data are obtained from experimentally measured temperatures in a stainless steel disk subjected to spray cooling.
