Abstract

Large Eddy Simulation (LES) of turbulent premixed combustion flow is performed by using the dynamic subgrid scale model based on -equation describing the flame front propagation. After introducing the LES governing equations with dynamic subgrid scale (DSGS) model newly introduced into the -equation, the turbulent premixed combustion flow over backward facing step is analyzed to validate present formulation. The calculated results can predict the velocity and temperature of the combustion flow in good agreement with the experiment data.

화염면의 전파를 모사하는 -방정식에 기초한 DSGS 모델을 이용한 난류 예혼합 연소에 대한 LES 해석을 수행하였다. -방정식에 새롭게 도입된 DSGS 모델을 적용한 LES 지배방정식을 고찰한 후 후향계단을 갖는 복잡한 형상의 연소기 내의 난류 예혼합 연소 유동을 고찰하였다. 본 연구의 LES 해석은 재부착 위치, 평균속도 및 변동량, 그리고 온도와 같은 실험결과를 정확히 예측하였다.
