A Navier-Stokes procedure has been developed to analyze the flow through candle-type ceramic filters. To obtain a quick but still realistic solution, the flow is assumed to be axisymmetric about a single filter unit. The porous filter wall is modeled by using the Darcy law while the standard k-ε turbulence closure. The choice of this turbulence model enables us to easily treat the ceramic filter unit of various surface roughness by simply adjusting the model constants. Sample calculations have been made for various flow dimensions, Reynolds numbers and varying degrees of surface roughness to identify the major parameters affecting the flow. These results represent code validation and a comprehensive parametric study. The velocity fields and the pressure drops for various cases are systematically presented in the thesis.
