The recent depletion of fossil fuel reserves and changes in the global environment led by an increase in atmospheric pollution are making people explore for renewable energy sources. Due to its many advantages over the traditional horizontal axis wind turbine (HAWT), such as its ease of maintenance, superior efficiency in wind farms, and lack of requirement for yaw control, the industry has been moving progressively in preference for vertical axis wind turbines (VAWT) in recent years. In this paper, computational fluid dynamics simulation with ANSYS Fluent software is used to study the effectiveness and performance of VAWT. This study uses the unsteady Reynolds-averaged Navier–Stokes (URANS) model to simulate three-bladed VAWT in 2D and 3D Environment. Using a three-bladed VAWT having fixed blade profile, rotor diameter, chord length, and setting angle, the current work systematically investigates the impact of various tip speed ratios (TSR) on VAWT performance (i.e., understands the effect of TSR on the efficiency). Subsequently, the TSR of 2, 2.5, and 3 are taken in order to understand its influence, after the results have been verified with the review of existing literature. To achieve optimal VAWT performance, it is imperative to choose a TSR within a specific range, as it significantly affects the numerical results.

摘要

The recent depletion of fossil fuel reserves and changes in the global environment led by an increase in atmospheric pollution are making people explore for renewable energy sources. Due to its many advantages over the traditional horizontal axis wind turbine (HAWT), such as its ease of maintenance, superior efficiency in wind farms, and lack of requirement for yaw control, the industry has been moving progressively in preference for vertical axis wind turbines (VAWT) in recent years. In this paper, computational fluid dynamics simulation with ANSYS Fluent software is used to study the effectiveness and performance of VAWT. This study uses the unsteady Reynolds-averaged Navier–Stokes (URANS) model to simulate three-bladed VAWT in 2D and 3D Environment. Using a three-bladed VAWT having fixed blade profile, rotor diameter, chord length, and setting angle, the current work systematically investigates the impact of various tip speed ratios (TSR) on VAWT performance (i.e., understands the effect of TSR on the efficiency). Subsequently, the TSR of 2, 2.5, and 3 are taken in order to understand its influence, after the results have been verified with the review of existing literature. To achieve optimal VAWT performance, it is imperative to choose a TSR within a specific range, as it significantly affects the numerical results.
