Test of flow field characteristics of the resembled model of concentrated wind energy turbine outside truck-mounted test and analysis

Due to the unique characteristics of the flow field of concentrated wind energy turbine, its characteristics of the flow field influence the performance of the concentrated wind energy turbine directly. Concentrating wind energy is in the purpose of using wind resource efficiently, raising the quality of the wind energy, increasing the output power and reducing the cost of per kilowatt. The 200 W concentrated wind energy turbine is the practical type that is converted from a model that had been tested in wind tunnel. The flow field of resembled model of 200 W concentrated wind energy turbine was tested outside in truck and the static pressure and total pressure of special point in each section was tested by Pitot and Digital pressure gauge, and the distribution of flow speed in the field was obtained. The test results show that it is 1.31 times faster than natural speed of wind where impeller installed in middle of the cylinder in the resembled model and the wind energy increases to 2.25 times of the natural wind flow. Through the analysis of the result of resembled model that was tested outside in truck, the regulation on speed distribution was found.
