Numerical Study of Wall Temperature Characteristic of a Platelet Transpiration Cooled Thrust Chamber

摘要：

The preliminary Numerical study of wall temperature characteristic of a platelet transpiration cooled thrust chamber is presented. By establishing a one-dimensional liquid-solid coupling non-equilibrium model and using the finites volume method, The temperature distributing of the platelet solid and coolant liquid by thickness of the thrust chamber are obtained. The affections of the wall temperature characteristic by several factors are calculated and analyzed, including the flux of coolant, the thermal conductivity of platelet material and the geometry structure of the cooling channels. The numerical results show that: The flux of coolant is the most important parameter of controlling the wall temperature; the thermal conductivity of platelet material should be chosen a moderate one,neither too large one nor too small one is of benefit to the whole performance of the thrust chamber;a much bigger width depth ratio of cooling channels is good to the conduction between the platelet and the coolant; The thermal exchanging efficiency in the cooling channels correlates with the flux of coolant and the thermal conductivity of platelet material.
