Title: PROPOSAL TO DEVELOP A NUMERICAL SIMULATION FOR THE INLET BUZZ PROBLEM BY SOLUTION OF THE TIME DEPENDENT NAVIER-STOKESEQUATIONS
Agency: NASA
Contract: N/A
Award Amount: $205,000.00
 

Abstract:

THE PROPOSED EFFORT WOULD DEVELOP AN APPROACH FOR THE SIMULATION OF THE EXTERNAL COMPRESSION INLET FLOW FIELD VIA THE THREE-DIMENSIONAL, TIME-DEPENDENT NAVIER-STOKES EQUATIONS. WITH THIS INNOVATIVE APPROACH TO THE PROBLEM THEENTIRE FLOW FIELD WOULD BE SIMULATED VIA A SINGLE SET OF GOVERNING EQUATIONS WHICH WOULD INCLUDE DETAILS OF THE WALL VISCOUS REGION AND INCLUDE BOTH STEADY STATE AND TIME DEPENDENT SHOCK SAVE - BOUNDARY LAYER INTERACTIONS. INCLUSION OF A TIME-DEPENDENT CAPABILITY ALLOWS APPLICATION TO THE INLET BUZZ PROBLEM. THE PROPOSED APPROACH AVOIDS USING DIFFERENT APPROXIMATE EQUATIONS IN DIFFERENT PORTIONS OF THE FLOW FIELD WHICH ARE THEN JOINED THROUGH A SET OF MATCHING CONDITIONS. THEREFORE, THE PROPOSED NAVIER-STOKES SIMULATION WOULD PROVIDE A MORE POWERFUL TOOL THAN CURRENTLYEXISTS FOR THE EXTERNAL COMPRESSION INLET PROBLEM. IN ADDITION, BEING GENERAL, THIS SAME APPROACH COULD BE USED FOR BOTH MIXED AND INTERNAL COMPRESSION INLETS. UNDER PHASEI A GENERAL THREE-DIMENSIONAL CODE WOULD BE MADE APPLICABLE TO THIS PROBLEM AND A DEMONSTRATION TWO-DIMENSIONAL CALCULATION WOULD BE RUN. ASSESSMENT OF THE PROCEDURE'S CAPABILITY WOULD BE MADE VIA A COMPARISION WITH EXISTING DATA.
