The Contrast Experimental Study On The Resembled Model Power Output Of Concentrated Wind Energy Turbines

The Concentrated Wind Energy Turbine (CWET) resembled modelâ…¢is based on the CWET resembled modelâ…¡, which straight line diffuser is changed as arc in modelâ…¢. The resembled modelâ…¢has no pressure board, and has shorter diffuser. The weight of modelâ…¢'s concentrated set is 54.7% lower than modelâ…¡.The aerodynamic characteristic of contrast experimental research is carried out by truck. The flow speed is 1.41, 1.42, 1.43 times faster than the speed of natural wind in modelâ…¡. The flow speed is 1.29, 1.32, 1.40 times faster than the speed of natural wind in modelâ…¢, which is 8.5%, 7.0%, 2.1% lower than modelâ…¡, flux energy is 23.2%, 19.6%, 6.2% lower than modelâ…¡.The power output characteristic of contrast experimental research is carried out by truck. When the load is resistance, the power output of modelâ…¢reaches 134.1W at 10.59m/s. When the load is batteries, the power output of modelâ…¢reaches 135.3W at 10.86m/s.When the load is resistance, the power output reaches 134.1W, the flow speed is 1.46 times faster than the speed of natural wind in modelâ…¡, the flow speed is 1.33 times faster than the speed of natural wind in modelâ…¢, which is 8.9% lower than modelâ…¡, flux energy is 24.4% lower than modelâ…¡.When the load is batteries, the power output reaches 135.3W, the flow speed is 1.43 times faster than the speed of natural wind in modelâ…¡, the flow speed is 1.32 times faster than the speed of natural wind in modelâ…¢, which is 7.7% lower than modelâ…¡, flux energy is 21.2% lower than modelâ…¡.
