Numerical Analysis of Combustion Flow Field during Line-Heating Process

Abstract

The aim of this study is to clarify the heat transfer from combustion flow field to plate surface during line-heating process. 3-dimensional computer code for the caluclation of combustion flow field is developed by taking into consideration of radiation heat transfer. Impinging turblent gas jet flames are numerically analyzed. In consequence, the flame structures formed near the jet nozzle such as under-expanded jet flames, corn flames at jet nozzle and the increase of both velocity and temperature of combustion are shown. And influence of the radiation heat transfer in the flow field is made clear.
