Numerical Analysis of Flow around a Wind Turbine Accelerator by Small Vertical Axis Wind Turbine
초록
영어
In this study, flow characteristic of small vertical-axis wind turbine was performed to analysis the numerical analysis. Blade geometry in the wind turbine is NACA 6512-43, and various degrees of the wind turbine accelerator were adopted. Numerical models are used for the analysis with CFD program of Ansys fluent and RNG k-e turbulence model was used. Rotational speed value of the wind turbine in analysis condition were obtained by the experiment. When the wind turbine accelerator is equipped, exit velocity of wind turbine accelerator tended to increases. Also RPM of wind turbine is increase. And maximum RPM appeared that wind turbine accelerator in degree 60° is equipped.
