Abstract:

SOME OF THE PROPOSED ENGINES SUCH AS THOSE BEING CONSIDERED FOR SPACE OPERATIONS USE REGENERATIVELY-COOLED NOZZLES FOR ENHANCING THEIR PERFORMANCE. THE EXPANDING GAS IN THE NOZZLE LOSES HEAT THROUGH THE WALL TO THE COOLANT FLOWING OUTSIDE THE NOZZLE IN A DIRECTION OPPOSITE TO THE NOZZLE FLOW. IN THIS PROCESS, BOTH ENTHALPY AND ENTROPY OF THE COOLANT GAS RISE, WHEREAS THOSE FOR THE NOZZLE GAS FALL. SINCE MEASUREMENTS ARE DIFFICULT AND COSTLY FOR SUCH ENGINESOPERATING IN VACUUM CONDITIONS, PROVISIONS WILL BE MADE IN THE ALGORITHM OF THE BOUNDARY LAYER INTEGRAL MATRIX PROCEDURE TO ACCOUNT FOR THIS. THE OBJECTIVE OF THE PROPOSED WORK IS TO RESOLVE THE ENTHALPY - ENTROPY CONSISTENCY ISSUES IN ORDER TO ACCURATELY CALCULATE THE FINAL PERFORMANCE OF SUCH ENGINES.
