Abstract:

THE NEED EXISTS FOR AN EFFICIENT HYPERSONIC INLET FLOW ANALYSIS CODE THAT WILL CALCULATE BOTH EXTERNAL AND INTERNAL FLOW FIELDS INCLUDING VISCUS EFFECTS. THE FIRST OBJECTIVE OF THE PROPOSED EFFORT IS TO DEVELOP A PROTOTYPE CODE BADED ON A PARABOLIZED NAVIER STOKES FORMULATION WITH A 3D PRESSURE EQUATION INCORPORATED IN REGIONS HAVING STRONG STREAMWISE ELLIPTIC EFFECTS. THE SECOND OBJECTIVE IS TO DEMOSTRATE THE CAPABILITY OF THE METHOD TO HANDLE THE CRUCIAL PROBLEM OF CAPTURING THE NORMAL SHOCK IN THE ELLIPTIC REGION IN THE INLET SIFFUSER SECTION. THE APPROACH IS TO DEVELOP A CODE THAT USES ANEFFICIENT MARCHING SOLUTION PROCEDURE. STARTING FROM AN INITIAL DATA PLANE, THE SOLUTION IS MARCHED IN THE DOWNSTREAM DIRECTION. FOR THE EXTERNAL DOMAIN AND A PORTION OF THE INTERNAL DOMAIN A SINGLE MARCHING PASS IS SUFFICIENT SINCE THE FLOW WILL BE AT HIGH SUPERSONIC MACH NUMBERS AND THE SOLUTION WILL BE HYPERBOLIC. IN ELLIPTIC REGINS MULTIPLE MARCHING PASSES WILL AN ELLIPTIC 3D PRESSURE EQUATION. AN INLET TEST CASE WITH ADEQUATE EXPERIMENTAL DATA WILL BE USED TO VALIDATE THE CODE FOR NORMAL SHOCK CAPTURING.
