Three-Dimensional Numerical Simulation of Secondary Side Flow Field in Steam Generator

Based on FLUENT program, and adopting the method of porous media, the calculation method of three-dimensional flowing was built in the condition of single-phase flowing in steam generator. By calculating three-dimensional flow field in steam generator in the process of nuclear plant steady running, the distributions of pressure and velocity were got. Finally, the flow field of numerical simulation was analyzed, and the result is satisfied.
