【Abstract】 The flow around secondary filter was analyzed with CFD software FLUENT and the resistance of filter was evaluated by using the output function resulted from this analysis.The flow field around the secondary filter was vividly characterized with a porous medium model,so that the flow pattern around this kind of filter was readily obtained.The surficial contour of the filter altered the fluid flow and,although the stiffening ribbing of the filter made local flow complicated,it played the role of flow guiding,instead.It was found by using it for sewage draining that the draining was unhindered.更多还原
