3-D Steady Analysis of Flow in CRDM Sewerage System

In order to obtain the flow state during sewer condition in Reactor and CRDM Sewerage system（RSE）, this paper analyzes the 3-D steady flow in RSE by using Computational Fluid Dynamics（CFD） method. In the premise that the pressure drop of the RSE is known, the mass flow rate, the velocity and the type of flow in the system is obtained with the inverse method, which is proposed and validated to be applicable in the paper. The result shows that in the sewerage conditions, the type of flow in the RSE is turbulence flow, which is helpful to sewer drain. The study results give an reference for the design of RSE.
