Abstract:
Heat transfer characteristics of regeneratively cooled attitude control engine thllJst chamber with MON一25／MMH pmpellant were studied．Firstly，heat transfer characteristics of thrust chamber waJl and regenerative coolant MMH were evaluated by the two dimensional heat transfer calculation code，then the three dimensional model was numerically simulated with the CFD soft— ware．The numerical results are well in agreement with the hot fire tests parameters of regenemtively cooled thlllst chamber with MON一25／MMH propellant at different working temperature of 298K and 243K．The results show that the numerical method can be used to evaluate the wall temperature，the heat nux thmugh the waU，and the temperature increase of coolant．The numerical results are ex． pected to be helpful for the design，especially for the design of regeneratiVely cooled attitude control engine thlllst chamber．
