Effect of Flows on the Evolution of Sprays and Combustion in Ramjet Combustor (I) : Ram Air Flows in Combustion Chamber

램제트 연소기 내 유동조건에 따른 분무 및 연소천이 (I) : 연소실 램공기 유동

With a view to estimating the effect of flows on evolving sprays and combustion in ramjet combustor and corresponding extent of combustion, ram air flows in combustion chamber is numerically experimented. Preconditioned three dimensional Navier-Stokes system of equations per transient, compressible, turbulent flows in IRR(Integral Rocket Ramjet) combustor is numerically integrated. Flow properties in the side-dump ramjet combustor, rectangular duct with two 60-deg curved inlets located radially at an angle of 180-deg, are addressed in terms of mixing quality and extent of combustion efficiency.
