IMPROVEMENTS IN THREE-DIMENSIONAL NAVIER-STOKES TWO-PHASE COMBUSTION COMPUTER MODELS

THE OBJECTIVE OF THIS PROPOSAL IS TO IMPROVE THE EXISTING REFLAN3D-SPRAY COMPUTER CODE TO PROVIDE A STATE-OF-THE-ART MODEL FOR SIMULATING ROCKET THRUST CHAMBERS. THREE MAJOR AREAS OF IMPROVEMENT ARE PROPOSED: (A) ACCURACY; (B) PHYSICAL REALISM; AND (C) COMPUTATIONAL EFFICIENCY. THEIMPROVED PHYSICAL MODELS TO BE INCORPORATED ARE: TRANSIENT CAPABILITIES, CONJUGATE HEAT TRANSFER IN COMBUSTION COOLING SYSTEMS, NEW SPRAY ATOMIZATION MODEL, MULTI-SCALE TURBULENCEMODEL AND MULTISTEP CHEMICAL KINETICS MODEL. DURING PHASE 1 OF THE PROJECT, CODE IMPROVEMENTS, NUMERICAL STUDIES AND VERIFICATION TESTS WILL BE PERFORMED. THE IMPROVED CODE WILL BE DELIVERED IN SOURCE FORTRAN.
