摘要

本文采用数值和实验方法研究了一个具有主动旋转元件(偏转板)的圆柱体模型的气动特性，该模型可作为风力机的工作叶片。数值模拟基于Ansys Fluent软件求解可实现湍流模型(\(k{-}\varepsilon\))的reynolds -average Navier-Stokes方程。在数值模拟结果的基础上，利用长205 mm、直径50 mm的圆柱体和直径100 mm的偏转板的实验室模型进行了实验研究。对模型的数值气动特性和实验气动特性进行了对比分析，识别了试验模型周围气流的气动特性。

AERODYNAMIC FEATURES OF A ROTATING CYLINDER WITH A DEFLECTOR

Numerical and experimental methods are used to investigate the aerodynamic characteristics of a laboratory model in the form of a cylinder with an active rotating element (deflector) that can be used as a working blade of a wind turbine. Numerical simulation was based on solving the Reynolds-averaged Navier–Stokes equations for the realizable (\(k{-}\varepsilon\)) turbulence model using the Ansys Fluent software. Experimental studies were performed using a laboratory model with a cylinder 205 mm long and 50 mm in diameter and a deflector 100 mm in diameter, which was produced based on the results of the numerical simulation. 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 model were identified.
