Abstract:

In the present paper, the coupling numerical analysis of 3D flow field and temperature field inside a marine generator was analyzed based on coupling field analysis method. The overall flow-temperature field models consist of the marine generator stator and rotor and flow passage and the air gap. Numerical analysis of flow-temperature field of marine generator were simulated by the finite volume method. The velocity and pressure distribution of fluid inside flow passage and the temperature field distribution of stator and rotor of marine generator were obtained. The present results showed that, the coupling field analysis method of overall flow-temperature field with air gap, stator and rotor can reflect the complexity of the air flow more clearly, and the value of flow and temperature field were more reliable. The results also contribute theoretical basis on optimization of ventilation struture of generator.
