3D Unsteady Aerodynamical Experiment & Validation of Cfd Simulations: Implementation of Rans & Urans Using Cfd Code Openfoam Faraz Habib

Not only the Europe but every continent is facing challenges to overcome energy crises and to provide better solutions. This research work is also the part of one of the most challenging tasks of European Commission-2020 Climate & Energy which undertook at Fraunhofer institute of Wind Energy and Energy Systems Technology (IWES). This is a downwind turbine project which is 3D unsteady aerodynamical experiment ( took at NASA AMES wind tunnel 2001) of horizontal axis wind turbine of phase VI baseline case of NREL USA and motivation of work package WP4 of IEA (International Energy Agency)-task number 29. The turbine with tower and nacelle is simulated using RANS and URANS. Local Angle Of Attack, Axial Induction factor, relative velocity, components of normal and tangential forces are calculated for 3D rotating blade. Discussion about 3D tower-blade interaction, boundary layer transitions and stall phenomenon has been done within this research work. This research work would be very exciting not only for better development in wind turbine design and performance characteristics but also for developing better CFD approaches to solve the flow near wall and to optimize the CFD methods.
