摘要
Abstract
In order to quickly and accurately compute the wall temperature distribution along the combustor axi-al line, a method to compute the temperature field of combustion chamber with active regeneratively cooling waspresented. On the condition of nonstationary wall temperature, the one-dimensional cooling model based on ref-erence enthalpy was established, and the distribution of the wall heat flux and the wall temperature along the combustor axial line were obtained at different mach numbers by using the heat transfer empirical equation. For the existing two types of cooling system structure, the cooling effectiveness of which was investigated through the presented method. And the satisfactory results obtained show the validity of the method.关键词
