Popis: | A method is developed to predict the aerodynamic forces on a circulation control elliptical airfoil in a twodimensional flow environment. By distributing source panels on the airfoil surface in the separation region and using conformal mapping techniques, a simple solution for the potential flow including effects of separated wake is obtained. The development of boundary layers and wall-jet is calculated by a finite difference method. The potential flow with separated wake effect calculations and boundary layer and wall-jet calculations are combined in an iterative process to determine the aerodynamic forces under given jet momentum coefficient and freestream condition. The effect of separated wake is found significant for a cylinder. The correlation of the calculation results with the available experimental data appears reasonable. |
