Numerical simulation of zero-head vertical-axis turbine with inertial force system

The paper is about the numerical simulation of blades on a Zero-head vertical-axis passive angle adjust turbine, which, is based on the CFD theory of unsteady viscous flow. According to the blade dynamic characteristics, balanced force equations and moment equations of blade are formulated. Based on the secondary development of commercial software, the mathematic model is set to simulate the working process of vertical-axis turbine with inertial force system. The numerical simulation results give the movement rule of blades and the energy efficiency characteristics of turbine. By the comparison between, numerical simulation results and experimental results, it shows that this method can predict the blades' motion and power efficiency characteristic of turbine effectively. Therefore, this research is significant for the design and application of vertical turbine using for the wind and ocean current energy
