Abstract

In this research the steady state analysis of a supercritical airfoil is done to understand the flow physics at transonic Mach number regime for various thickness. The modeling of NASA SC (2) 0714 supercritical airfoil with various thickness values is done. The steady state analysis is carried out for different test cases in combination with different thickness, angle of attack and Mach number at 10 km altitude using density-based Reynolds Averaged Navier Stokes solver and k-omega Shear Stress Transport Model. The variation of pressure and velocity is studied with different Mach numbers and given angle of attack. The pressure and velocity counters clearly indicate the formation of shockwave and its location. The results show that the occurrence of shock wave and its location on the surface of the airfoil. The strength of the shockwave formed is affected based on the thickness of the airfoil, the freestream Mach number and the angle of attack. The strength of the shockwave has decreased with decrease in the thickness of the airfoil at given angle of attack and Mach number. Also, the location of the shockwave has
