Performance analysis of VAWT with H-darrieus rotor using gurney flap Available to Purchase

This paper presents a two-dimensional (2D) computational fluid dynamics (CFD) study of a straight vertical axis wind turbine (VAWT) using gurney flap. The purpose of the study is to use CFD simulation to look into the VAWT’s performance and flow characteristics. The simulation represents the geometry of the turbine, the cfd boundary condition that is involved, the meshing, and the solver process parameters in order to shed light on the velocity and pressure distribution surrounding the turbine, as well as the power coefficient and overall efficiency of the turbine. The outcomes demonstrate that the current simulation model has ability to anticipate the VAWT’s performance with accuracy and offer useful data for the turbine’s design and optimization. Additionally, it was discovered that the model’s conversion coefficient rises with an increase in the tip-speed ratio (TSR), reaches a maximum at roughly two TSR, and subsequently falls. Regarding torque output, a comparable pattern was also noted. But when the TSR rises, the torque coefficient falls. Overall, the study shows that CFD is a valuable tool for VAWT analysis and design in wind energy applications.
