This technology adopts the aerodynamic principle, and simulates the wind tunnel with vertical axis rotation. The blades are in the shape of aircraft wings, so that the efficiency of the wind wheel will not be affected by deformation when it rotates. It is composed of 4-5 vertically arranged blades, and the wind wheel is composed of a connecting rod fixed with a 4-angle or 5-angle hub and connected with the blades. The wind wheel drives the rare earth permanent magnet generator to generate electricity, which is sent to the controller to control and transmit the electric energy used by the load.
According to the gas strip theory and technical principle, the tangent plane perpendicular to the fan shaft can be selected for model calculation. According to the actual size of the blades, the distance between the rotating shafts of each blade is n meters. CFD technology is used to calculate the simulated aerodynamic coefficient, and discrete numerical method is used to solve the aerodynamic force of airfoil section. The grid method is used to compare the vortex distribution of Reynolds number flow, and the main results of numerical simulation calculation of Naville-Stokes equation at high Reynolds number are formed.
Based on the power generation principle of rare earth permanent magnet materials, combined with the mechanics principle of wind wheel and air hole, the direct-drive structure is used to generate power by rotation.
