Research on Calculation Ventilation Cooling of Generator of Bulb-stator Turbine

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.
