Title: Numerical simulation of vertical axis wind turbine with cambered airfoil
Abstract: A numerical analysis of the aerodynamic performance of the vertical Axis wind turbine with 4 cambered airfoil profile is presented.For the numerical analysis of the wind turbine,the finite volume method and SIMPLE algorithm of the computational fluid dynamics are used with SST k-ω turbulence model and moving mesh technique.The findings of this paper are expected to be helpful in developing the vertical axis wind turbine with cambered airfoil in the near future.From the results,the instantaneous torque coefficient of each rotation blade is between-0.03 to 0.18 when the inlet velocity is 10 m/s and the tip speed ratio is 1.6.The maximum torque coefficient of the wind turbine is attained when the tip speed ratio is around 1.6.The power coefficient reaches the maximum value as the tip speed ratio is approaching 1.7.
