【Abstract】 Based on the theory of blade element momentum, a double round plate-multiple stream tube mathematical model was established using Matlab/Simulink program, which could analyze aerodynamic characteristics of H-type vertical axis wind turbine. The attack angle characteristic,tangential force characteristics,normal force characteristics for different solidity and tip speed ratio of wind turbine were obtained using the mathematic model,which were compared with experiment data and the result of single stream tube model. The results confirm that the method is accurate and superior.更多还原
