analysis of small vertical wind turbine having h-darrieus blades with stall delay model

摘要: Several models, about the power performance prediction for Darrieus wind turbines, have been developed during last decades. Among these an enhanced multiple stream tubes model, LDWT (Lee-Darrieus Wind Turbine model) turbine blade with experimental aerofoil characteristics showed simple, fast, and precise results, without time consuming, of solving Reynolds Averaged Navier-Stokes equation complex air flow passing through rotational blade. Recent interest has paid on straight rotor (H-Darrieus rotor) because its several advantages over curved blades. However, few reports cover model. In this paper, was extended into H-Darrieus 2-dimensional data stall delay From results high solidity rotor, underestimate test but it shows dramatically well matching when delaying is calculated additionally in Therefore, shown that model can be used design analysis H-type vertical equation.
