A method is presented to calculate the low-speed incompressible separated flow around multi-element aerofoils. The geometries of multi-element aerofoils in the physical plane are completely arbitrary and are transformed into multiple circles in the computational plane by a conformal mapping technique. Jacob's model, which distributes sources on the separated surfaces of multi-element aerofoils to simulate the effects of separation, is adopted here. The position of the separated point and the pressure on the surfaces of multi-element aerofoils are calculated by iteratively coupling the potential flow and boundary layer. The effects of the boundary layer are simulated by modification of the boundary condition. All iterative procedures converge rapidly as a result of using the fast Fourier transform (FFT) technique. |
