Abstract

IN THIS RESEARCH, FLOW IS SIMULATED NUMERICALLY THROUGH AND AROUND A MIXED-COMPRESSION INTAKE TO INVESTIGATE EFFECTS OF CORNER ROUNDING ON INTAKE PERFORMANCE AT FREE STREAM MACH NUMBERS OF 1.8, 2 AND 2.2 AND AT ZERO DEGREES ANGLE OF ATTACK. FURTHERMORE, EFFECTS OF DIFFERENT MACH NUMBERS AND BACK PRESSURES ARE STUDIED. TOTAL PRESSURE RECOVERY (TPR), FLOW DISTORTION (FD), MASS FLOW RATIO (MFR), AND DRAG COEFFICIENT (CD), ARE CHOSEN AS THE INTAKE PERFORMANCE PARAMETERS. CFD RESULTS ARE VALIDATED WITH EXPERIMENTAL DATA. RESULTS SHOWED THAT INCREMENT OF BACK PRESSURE GENERALLY CAN IMPROVE THE PERFORMANCE WHILE INCREASING MACH NUMBER HAS UNFAVORABLE EFFECTS ON TPR. ALSO APPLYING FILLET CAN SIGNIFICANTLY IMPROVE PERFORMANCE PARAMETERS OF FD&NBSP;AND MFR. HOWEVER IT DOESN'T TPR&NBSP;AND CD.
