摘 要：Experimental and numerical investigations on a cooling liquid-film flow in a hot-fire environment within a model combustion chamber were carried out to characterize the flow and heat transfer phenomena and to provide insight into flowfield and guide the evolution of the cooling design.A model combustion chamber with optical windows was set up for shadowgraph imaging of the liquid *** simulations using a separate-phase VOF method of the liquid-film flow and the combustion of the gaseous oxygen and methane were conducted to characterize the cooling-film flow and heat transfer between the hot combustion products and the liquid film.
