Abstract
The present Bachelor thesis studies, develops and validates the Vortex Cloud Method in a 2-dimensional domain. This method is able to model the flow over a body accounting with flow separation and therefore, overcomes the main limitation of the classical potential models, where flow detachment is not allowed. The Vortex Cloud Method is a meshless model that computes the solution by solving the Navier Stokes Equations through several steps. First, the surface of the evaluated body is discretized in panels and the vorticity of each panel is obtained through potential methods. The next step consists on concentrating the vorticity in discrete vortices and shed them at a certain distance of the surface. After that, the free discrete vortices are convected under the influence of other vortices, the surface vorticity and the free stream. Moreover, viscous diffusion is simulated by a applying a random displacement to the vortices. Finally, the pressure coefficient distribution along the body surface is computed as well as the resulting force coefficients that determine the aerodynamic behaviour of a given body. The theoretical bases of the method and the implementation of each step are extensively explained in this work. Moreover, the implemented model is validated and discussed through the comparison of the results with experimental data.
