摘    要:为研究风载荷对碟式太阳能聚光器的影响,基于CFD流体动力学分析软件,建立碟式太阳能聚光器风载仿真计算模型,分析聚光器风载作用下的流场,计算聚光器的平均风力系数和风力矩系数,并研究聚光器风力系数和风力矩系数随不同方位角和高度角的变化规律。研究结果对开发碟式太阳能聚光器、优化聚光器的避风控制策略,以及提高太阳能电站风灾害的抵抗能力具有重要的参考意义。

Abstract: In order to study the influence of wind loads on dish solar condenser, a simulation model of the dish solar condenser was established under wind loads based on CFD fluid dynamics analysis software. The flow field of the condenser under wind load was analyzed, and the average wind load coefficients and wind torque coefficients were calculated. In addition, the variations of wind load coefficients and wind torque coefficients with different azimuth angles and altitude angles were investigated. The results have great reference significance to the development of dish solar condenser, optimizing the condenser sheltered control strategy and improving the resistance of the solar power station wind damage.
