Özet

A 2d numerical study has been conducted by using Ansys Fluent 2020R2 program to design 4 different cases(shapes) for buildings at a different initial velocity value (2,4,6 m/sec) .in order to find a way to benefit from the areas where the winds velocity is small and it not enough to operate the winds turbines. Where a velocity analysis has been carried out for the four cases, each of them separately, and the intensity of turbulence and pressure around the buildings has been calculated. The highest velocity has been obtained at case 3, where the velocity has been reached to 4 m/sec when Vinlet was equal to 2m/sec. The best case has been determined and the streamline and the vector for velocity have been presented for the best case. The area between the two buildings has been divided to six parts. for the best case of the buildings in order to find the area where the velocity flow is high to put the wind turbine . The dimensions, height and initial velocity for appropriate turbine ,have been determined. The initial and final velocities of the used turbine have been determined. Also, the annual energy calculations have been found to increase the speed by using the Weibull distribution. finally it has been determined the annual energy production for the selected region for the first case(region without two buildings) was 68 kWatt hours, but this value increase to 294 kWatt hours in the new case (the region when putting two buildings). That means, the power was increased by 76%.
