Flux Marching Method for Two-Dimensional Inverse Heat Conduction Problems in the Water Impingement Cooling

Abstract

Numerous experimental and numerical investigations have been done to uncover the essence of the complex cooling process using circular water jet or planar curtain water jet in steel industry. In this study, the cooling characteristics of water jet, especially the progression of water cooling zones, is described. A new approach named “Flux Marching Method (FMM)” is developed to better suit the features of impingement water cooling. Numerical tests verified that FMM more accurately reflects the actual cooling process in impingement cooling by taking the water movement into account. Special considerations in implementing FMM are discussed.
