主　　题：3D turbulent flowfield N-S equations with Darcy's law 

摘      要：Time-averaged explicit Navier-Stokes equations with the modified Darcy’s law for the threedimensional cylindrical flow field were formulated to the problem. Numerical investigation of the effects of the face velocity on ceramic candle filter was executed in three-dimensional turbulent flow field. It is found that the flow in the vessel is pushed toward the filter region by the pressure difference between inside and outside of the filter due to the viscosity and inertial resistance. It is also found that the pressure drop is directly proportional to the flow rate and the slope of the pressure drop will be mitigated when the thickness of the filter cake (8) is larger than 10 mm.
