Abstract

Vertical Axis Wind Turbines has been looked upon by researchers as a potential avenue for power generation at domestic level. The Coefficient of Power of Vertical Axis wind Turbine has its limitations mentioned by Betz theory. In this paper three configurations viz one stage, two stage and three stage Wind booster has been designed, modelled and numerically analyzed. A Multistage concept of flaps has been used in wind booster so that wind velocity may increase during each stage. The performance of turbine is assessed by wind booster for Flow velocity, Pressure. For Numerical analysis SST K-epsilon turbulence model has been used. From the analysis it is found that, the two stage wind booster velocity and pressure magnitude range is superior as compared to other two configurations.

垂直轴风力机创新增压器结构的数值分析
垂直轴风力发电机已被研究人员视为一种潜在的国内发电途径。贝茨理论指出了垂直轴风力机功率系数的局限性。本文设计了一级、二级和三级风助推器三种构型,并对其进行了建模和数值分析。增压器采用多级襟翼的概念,使风速在每一级都能增加。通过风力增压器对风力机进行风速、压力等性能评价。数值分析采用了SST K-epsilon湍流模型。分析发现,两级风助推器的风速和压力量级范围优于其他两种配置。
