| Abstract: | The internal regenerative cooling is a new cooling technique of the thrust chamber.Up-to-date,it has not been used yet in our country.In this paper, a physical and mathematical model of the internal regenerative cooling is presented, and a numerical calculation of two-dimensional temperature field in the th-ruster wall is conducted emphatically under different parameters such as coolant flow rate near the wall, material and wall thickness.The calculation results are also analyzed and discussed. |
