Computational Studies on Airfoil for Micro-Capacity Horizontal Axis Wind Turbine

Received Date:12 May 2021, Accepted Date:02 August 2021, Published Date:07 September 2021


Objectives: To design a blade profile suitable for a micro-capacity wind turbines. To analyze the performance of a new blade profile in terms of lift to drag ratio using simulation software such as QBlade and ANSYS Fluent CFD. Methods: A new airfoil for a micro capacity horizontal axis wind turbine is designed using QBlade software. A 3D model of the airfoil is prepared using CATIA. 2D and 3D CFD simulations of this airfoil are carried out using ANSYS Fluent and the simulation results are compared with those obtained from QBlade. Findings: It is found that QBlade results for the lift to drag ratio fairly match with the experimental results at all values of angles of attack (0◦ to 20◦). 3D CFD results also fairly match with experimental results at lower values of angles of attack (0◦ to 3◦). The optimum value of lift to drag ratio is obtained for the angle of attack of 3◦-4◦. 3D CFD simulation under predicts lift to drag ratio at higher angles of attack as compared to the experimental values. Novelty: The study reports simulation results for an airfoil blade profile of a micro-capacity wind turbine using both QBlade and ANSYS Fluent CFD (both 2D and 3D). The simulation results fairly match with the available experimental results.
