난류 예혼합연소 화염의 LES 및 산업용 연소기 개발을 위한 LES 응용 해석 기술

LES OF TURBULENT PREMIXED COMBUSTION FLAME AND LES APPLICATION FOR THE INDUSTRIAL COMBUSTOR DEVELOPMENT

LES results of turbulent premixed combustion flows are introduced by using the dynamic sub-grid scale model based on G-equation describing the flame front propagation. The turbulent premixed combustion flows around bluff body and over backward facing step are analyzed to validate present formation. LES of swirling partially premixed combustion flame is also performed to conform the predictive capabilities of LES model and to prompt our understanding for the combustion flows over double cone swirl burner combustor by using CFD-ACE+ commercial code.
