| Abstract: | The three-dimensional liquid-solid coupling mathematical model for the heat transfer of platelet transpiration- cooling thrust chamber was established.Heat transfer characteristics of platelet cell affected by the geometry structure,the materials physical characteristics,and the coolant were simulated numerically.The design scope of coolant depth ratio of allocated platelet,the conductivity of platelet material and thermal behaviors of platelet cell with different kinds of coolants were obtained.The calculation results supplied important design values for platelet transpiration-cooling thrust chamber. |
