Abstract

In this research, an aerodynamic analysis code for a vertical-axis wind turbine (VAWT) was developed. The aerodynamic characteristics of the VAWT was modelled by the double multiple streamtube (DMS) model for more accurate results and faster computation time. Based on the structure of AeroDyn, developed by the NREL and used to calculate the aerodynamics of a horizontal-axis wind turbine, an in-house code was constructed and solved the aerodynamic characteristics with steady-state wind. For validation of the in-house code, a reference code called QBlade that employs the same aerodynamic model was used to calculate the aerodynamics of the VAWT. For validation of aerodynamic characteristics computed by in-house code, three characteristics of power coefficients, angle of attack and rotor torque were selected and the errors with QBlade were calculated and compared. As a result, the validity of the in-house code with an error rate of about 0.1% for the three characteristics was verified. The results of these two codes corresponded with each other despite small differences.
