Measurement and calculation of blade surface pressure for a wind turbine in field
摘要
Abstract
A measurement method of the blade surface pressures for a wind turbine in field is given and the measured data are compared with the CFD calculation results in this paper. For the field experiment, the belt sensors were mounted on seven sections along the blade to collect the pressure signals in unsteady environment. For the calculation, the incompressible N-S equations coupled with the SST k-ω turbulence model are solved to obtain the aerodynamic performance of the tested blade airfoils, whose geometric shapes have been determined from digital scanning. From the comparison between the experiment and calculation, it is demonstrated that the pressure distribution on the rotational blade appears obviously different from the two-dimensional airfoil data due to the three-dimensional rotational effect and validated that the wind turbine power output could be underestimated if the two-dimensional airfoil aerodynamic data based on the blade momentum theory are used.关键词
