Numerical Simulation of Condenser Combining with Low-Pressure Exhaust Hood and Condenser Throat

Abstract:

In order to obtain the more real condition of the flow field at condenser, the commercial software FLUENT is used to simulate the flow field of the condenser tube bundle area, alone or coupling with the low-pressure exhaust hood and condenser throat. The analysis indicates that the calculation result of combined model is different from the single calculation result of condenser tube bundle area. The flow field of condenser tube bundle area is strongly influenced by low-pressure exhaust hood, the frustums diffuse-angle, the low-pressure heater and the injection of the exhaust steam from the small turbine. The uneven velocity distribution at the outlet of the throat has great influence on the heat exchange of condenser tube. Combined numerical simulation gives more reasonable result.
