Abstract

Numerical and experimental methods are used to investigate the aerodynamic characteristics of a laboratory sample in the form of a cylinder with an active rotating element - a deflector-that can be used as a working power blade element of awind power plant. Numerical simulation was performed using the Ansys Fluent software based on the Reynolds-averaged Navier-Stokes equations supplemented by a realizable (κ-ε)-turbulence model. Based on the results of numerical simulation, a laboratory model with a cylinder 205 mm long and 50 mm in diameter and a deflector 100 mm in diameter was made for experimental studies. A comparative analysis of the numerical and experimental aerodynamic characteristics of the model was carried out and the aerodynamic features of the airflow around the test sample were identified.
