The analysis project is a poster presentation. However, I am required to build a simulation using the CFD Ansys Workbench under which I should determine the effects of the sand particles on two aerofoils which are NACA 2412 and NACA 2415. Hence a simulation should be designed to include the mesh generation, graphs and results in different fluid flow scenarios using workbench for both aerofoils as well as explanation given in a poster.
