Research abstract
ONE OF THE MOST IMPORTANT ISSUES IN DEVELOPING COMPUTATIONALFLUID DYNAMICS FOR HYPERSONIC FLOW IS TURBULENCE MODELING. ONE OF THE UNIQUE ASPECTS OF HYPERSONIC FLOW IS THE EFFECT OF THE SHOCK WAVES ON TURBULENCE, AN EFFECT THAT IS CONSIDERABLE. PREVIOUS WORK HAS FOUND THAT CURRENT TURBULENCE MODELS DO NOT REPRESENT THE INTERACTION OF THE SHOCK MOTION WITH THE TURBULENCE AND THAT THIS INTERACTION IS CONSIDERABLE. THE PROPOSED WORK IS CONCERNED WITH DEVELOPING A TURBULENCE MODEL TO ACCOUNT FOR THIS PHENOMENON.
