Optimization of the Energy Capture Performance of the Lift-Drag Hybrid Vertical-Axis Wind Turbine Based on the Taguchi Experimental Method and CFD Simulation

In order to improve the energy capture performance of vertical axis lift wind turbines in a low speed environment, drag turbine is employed couple with design existing turbines. contrast literature, this work, computational model proposed that can simulate interaction between and fluid. The effects pitch angle (β), installation (θ), overlap ratio (ε) diameter (DL) on hybrid are systematically analyzed based Taguchi CFD methods. results show under optimized parameter combination, peak coefficient lift-drag be increased 0.2328, compared 0.0309 0.0287 pure turbine, respectively. addition, result prototype test not only has better-starting but also 2.0 times output power turbine.
