SUPERSONIC FLOW OVER DOUBLE CIRCULAR ARC AND EDGE AIRFOIL
With the given task, the numerical part and simulation part have to be completed separately and after the results it has to be compared whether the commercial codes in CFD is using working turbulence models.
The numerical analysis part has to be started by understanding the given data. The theory about the given data then have to be analyzed and calculated with right understanding of the formulas.
The sequent for the solving the task would be started by geometrical analysis of the airfoil. Thickness of the airfoil could be found easily with geometry.
After determining the thickness of the airfoil, location of the leading edge shocks has to be study. Strength of the shock could be determined after the study of the pressure difference after the shock over entrance pressure of the shock.
Lift and drag coefficient could be calculated by only neglecting the expansion waves caused by the bi-conical surface. As the area and pressure varies by the geometry, differential calculations are used in order to calculate both drag and lift coefficient.
