2차 공기 주입각도에 따른 소각로 내부의 재순환 영역 변화 = The change of recirculation zone with the inlet angle of secondary air in an incinerator

다국어 초록 (Multilingual Abstract)

The purpose of this research is to find out how the inlet angle of
secondary air affects the formation of recirculation zone inside a small
incinerator. A commercial code, PHOENICS, is used to simulate the flow
field of an incinerator. The computational grid system is constructed by
Multi-Block technique. Numerical experiments are done with the five
different angles of secondary air inlet. The formation of recirculation
zone is evaluated by checking velocity fields. The computational results
show that recirculation zone is clearly formed from 60 degree of inlet
angle and the zone of recirculation is widen as angle of recirculation is
increased to 75˚.
