In order to optimize the layout of horizontal axis marine current turbines and improve its overall efficiency,the flume experiment was conducted to investigate the law of the wake formed by the interaction between the horizontal axis marine current turbine and the flow.In order to study the wake effect,the variation process of flow velocity was measured under different initial velocities and thrust coefficients.The outcomes show that in the direction of flow,the faster the initial velocity is,the larger the convergence value of wake is;the influence scope of the thrust coefficient is within the distance of five times disk diameters.At a distance of fifteen times disk diameters,the wake velocities become stable and the convergence value is identical with the thrust coefficient varying.In the vertical direction of flow,the scope of the wake effect becomes larger with faster initial velocity;the influence scope of the thrust coefficient is in the range of four times disk diameters.
