| Guidelines |
| To calculate the unsteady aerodynamic flow over wind or lifting surface the boundary element method, e.g. the panel method, can be used. However, the panel method alone cannot simulate the flow separation and also doesn’t account for the viscous effect which is very important in unsteady load calculation. Therefore, the proposed master thesis will focus on the development of a hybrid boundary element method which can be fast compared to CFD and can simulate the viscous effect using the boundary layer theory and the shear layer separation will be modeled using the 3D vortex particle method. This kind of tool has promising application in rapid calculation of load for aeroelastic analysis in power turbine blade cascades, wind turbines or for estimation of rotor craft load. The master student will spend time to read the state of the art and formulate an algorithm to model the flow field around a wing and blade cascade. For the numerical implementation MATLAB, Fortran, C/ C++, or Python can be used depending upon the choice. |
