Flow Characteristic Analysis in Accordance with Geometrical Modification of Air Distribution Plate in Gasboiler Combustion Chamber

가스보일러 연소실 공기분배판의 기하학적 형상에 따른 유동특성 해석

This paper reports a numerical flow characteristic analysis in gas boiler combustion chamber. The numerical results with simplification and assumptions were found within 30% of the experiment. A lot of geometrical modification has been invested in attempt to obtain the uniform flow in the combustion chamber exit. As a result, the velocity magnitude of the combustion chamber is relate with the hole size in air distribution plate. The velocity uniformity of the combustion chamber is relate with the number of holes and location in air distribution plate.
