摘要
本文采用多学科理论和数值计算相结合的方法,从损耗的角度对灯泡贯流式水轮发电机内部流体场和温度场的耦合关系进行研究,建立了灯泡贯流式水轮发电机三维流体场和温度场的数学模型,采用有限元法计算灯泡贯流式水轮发电机的流体场、温度场,以及二者的耦合关系,为灯泡贯流式水轮发电机的通风冷却系统的设计以及结构优化设计提供了理论依据。
In this paper, the research on relationship between internal fluid and temperature fields is given to generator of bulb-stator turbine which is adopted a muhidisciplinary theory and numerical combination of methods, from the perspective of loss, as well as a three-dimensional fluid and temperature fields of mathematical models. By finite element method, the field of fluid, temperature, and the coupling relationship are calculated, which provides a theoretical basis for generator of bulb-stator turbine on the ventilation cooling system design and structural optimization and design.
