The disastrous effect of climate change has motivated scientists and engineers around the world to reduce dependency on fossil fuels. Among many alternative sources of energy, power production by wind energy has increased exponentially for last few years. Along this spectrum, efforts are made to investigate the possibility to install wind turbine on high roof tops. The onsite generation will also help to integrate micro wind turbines with urban areas. The proposed research work focuses on the CFD study of a Vertical Axis Wind Turbine (Troposkien-shaped) mounted on the upstream edge of a building, so that flow acceleration generated by the edge of the building contributes to enhance performance of the turbine. The CFD methodology validation is done by comparison of performance with experimental data. Geometric configuration of Sheldahl’s models is used for unsteady 3D flow of roof mounted Troposkien wind turbine. Three different turbine placement positions at different heights are investigated to observe Cp - λ curve sensitivity at various tip speed ratios. Position 1 and Position 2 are at the edge of the building, whereas position 3 is a few meters away from the edge, directed towards the geometric center of a building. To simulate realistic atmospheric wind conditions, wind gradient is imposed at the inlet, with fixed desired velocity pointing to the middle of the wind turbine. Geometry and numerical setup is described in details, along with the obtained results. The optimal placement position of the turbine shows improvement in the power coefficient from 0.33 to 0.4 at low wind speeds.
