This is the so-called compression work effect. Therefore this air gets compressed and its pressure increases which enhances the lift. At relatively small height, the air below the airfoil does not have sufficient space to escape due to the blockage from the ground as the airfoil moves downwards towards the ground. Furthermore in this region, in addition to SGE and incidence effect, the compression work effect becomes very important. In the small height region, the lift in DGE increases rapidly with decreasing height and is significantly larger than that in SGE with the same angle of attack. Both SGE and the incidence effect due to sinking govern the flow field. In the medium height region, the lift in DGE increases with decreasing height and is almost equal to the lift in SGE with the same angle of attack. Ground effect is insignificant and the physics that governs the flow is due to the incidence effect induced by the sinking movement. In the large height region, the lift in DGE does not change with decrease in height and is equal to the lift in static ground effect (SGE) with the same angle of attack. Analyses of the results show that DGE can be divided into three regions based on the aerodynamics and flow physics which depend upon the ride height above the ground. Several sink rates are imposed on the airfoil. 15 kW, while wind turbines with NACA 4412 have Cp turbine performance. And CFD analysis is carried out using FLUENT 6.3.26.
