Force and CFD Analysis of Wind Turbine Blades

Abstract

In order to better design blades and prevent from resonance of blades fatigue damage, it is necessary to analyze the force and CFD of the blade. Assuming that the blades are in a static state, and make the air is blowing at the same relative velocity from the opposite direction to the blades, aerodynamic force and inertial force are analyzed. By simulating the flow field around the blades, wind turbine surface and ambient air flow condition can be obtained. The results show that the force at the root of the blade is the biggest, and the bending moment is also the greatest.
