Renewable energy resources are promising in power generation due to their sustainability aspect and environment friendliness as they are means of pollution free power production. Wind energy.y is utilized for power production with the help of wind turbines. The offshore and onshore windfarms consisting of horizontal axis wind turbines are major contributors in the wind energy. However, this type of turbine is not domestically viable mainly due to limitations of directionality and noise. Vertical axis wind turbines do not have these constraints and may blend in the urban environments. In built environments, the wind flow is quite complex due to large scale effects and turbulence. In this paper, the academic building of a university is studied as a possible platform for harnessing the wind energy resources. This case study is performed on academic blocks of University of Gujrat. These building environments were modeled and analyzed with computational fluid dynamic software to model the wind behavior on the building roof top. These results show that there is potential in setting up micro windfarms for the academic environments. The simulation for single building showed a potential for 61.8kW whereas this potential decreased substantially when terrain effects are considered using the circular arrangement for the simulation.

Vertical-axis wind turbine (VAWT) configurations expose the airfoil sections of turbine blades to angles of attack between 0° and 360°. In designing new VAWT configurations or improving existing configurations, some knowledge of the aerodynamic forces at these angles must be known. This paper presents a model for predicting 360° of aerodynamic forces acting on the s1210 airfoil at two low Reynolds-number conditions. This model is based upon results from wind-tunnel experimentation and achieves a close approximation of the measured performance of the airfoil. Models such as this provide the means to predict airfoil lift and drag characteristics and use those results to predict the thrust capabilities of the airfoil as the turbine blades rotate. The model is presented and compared with other post-stall models within the literature. These comparisons show that this model is superior to previous models when applied to the s1210. The model shows that two angles of attack regions between 0 and 30° and then again those between 180° and 300° provide the highest thrust contributions of the airfoil. Using models such as these for system-level analysis provides the means to assess the feasibility of different VAWT configurations. Furthermore, it provides the means to assess the proper spacing and distance between turbine blades to generate the desired thrust. This enables the designer to determine the optimum turbine geometry in order to maximize performance.
