Characteristics of Wind Forces acting on a Standstill Wind Turbine

Abstract

In this paper we describe the characteristics of wind forces acting on a propeller-type standstill wind turbine with three blades. The wind forces were investigated using wind tunnel tests. The test parameters were wind tunnel flow (grid turbulent flow and uniform flow), pitch angle of the blades, stationary blade positions. As a result, the wind force coefficients acting on the standstill wind turbine at a position where one blade corresponded to a tower were differed from those at the other blade positions.
