AERODYNAMIC HEATING UPGRADE OF THE PARABOLIZED NAVIER-STOKES(PNS) CODE

THIS EFFORT WILL ENHANCE THE CAPABILITY OF THE AIR FORCE PARABOLIZED NAVIER STOKES CODE (AFWAL PNS CODE) TO PREDICT SKIN FRICTION AND HEAT TRANSFER TO HIGH SPEED FLIGHT VEHICLES. THE CURRENT PREDICTION TECHNIQUES REQUIRE EXTREMELY ACCURATE CALCULATIONS OF VELOCITY AND TEMPERATURE IN THE VICINITY OF THE WALL. THE EFFORT HERE WILL REPLACE THIS PROCEDURE BY USING INTEGRAL MOMENTUM AND ENERGY EQUATIONS WHICH DO NOT REQUIRE THE EXTREME ACCURACY OF THE FLOW PARAMETERS NEAR THE WALL. THREE DIMENSIONALITY WILL BEACCOUNTED FOR BY DETERMINING THE METRIC COEFFICIENT AND USING THE AXISYMMETRIC ANALOG.
