Wind gradient impact on the potential wind energy profile based on the ground launch

In general, aerodynamic barriers can be affected by wind gradients in wind flows. Besides, the wind speed will increase with increasing altitude above the ground. Flow near the surface encounters obstacles that can reduce wind speed. Technically, the reduction in a speed close to the surface is a result of the function of surface roughness. In addition, the wind speed is very different for different types of terrain. However, this condition will also give random effects on the vertical and horizontal velocity components in the main flow direction, as discussed in these studies. These works are subjected to evaluate the wind gradient impact on the wind energy profile considering the ground launch on various levels. Specifically, wind gradients are modeled and approached by shifting vertical velocities which are designed in various exponential coefficients that refer to the type of surface. The results show that the gradient has a significant effect on changes in wind speed patterns that are in line with potential changes in the generated energy. The ground launch also leads to the energy profile as presented on the speed at the high.
