摘要
对太阳能热气流电站中的涡轮机进行了设计和数值模拟。建立了涡轮机区域流体流动的物理数学模型,并对其进行数值模拟;研究了涡轮机的转速与压降对涡轮机的流量、输出功率和能量转换效率的影响。通过与相近实验模型的试验结果对比,证明了设计方案和数值模拟方法是有效的。
The turbine of the solar chimney power plant system has been designed in this paper. A mathematical model and a physical model have been developed to describe the flow of the turbine region. Furthermore, the effects of rotation speed and pressure drop of the turbine on the mass flow rate, output power and efficiency of the system have been studied. The simulation results show that the methods of design and numerical simulation are valid by comparison with the experiment of the prototype. It provides a theoretical reference to the design on the turbine of the large-scale solar chimney power plant systems.
