| Abstract: |
| To explore the influence of the filter model on the flow field of the mesh filter，this study used CFD software to simulate and calculate two different types of filter models under different filtration flow rates for the flap mesh filter. The test values were compared,and the flow field and pressure field inside the filter screen were analyzed. The results showed that the porous step model had the characteristics of less time\|consuming and high efficiency, and the time\|consuming value of the porous step model was about 1/6 of that of the simplified three\|dimensional filter model. The flow field and pressure along the x\|axis of the porous step model and the three\|dimensional filter simplified model showed a gradually decreasing trend. Analyzing the simulation values of flow velocity and pressure at the interface of porous media found that the simplified three\|dimensional filter model simulated better the blocking effect of the mesh structure of porous media in engineering. The three\|dimensional filter simplified model reduced better the influence of the medium structure parameters on the head loss.The porous step model worked better to reduce the relationship between the medium overflow and the head loss. This research can provide a reference for the selection of high\|precision and high\|efficiency models considering the characteristics of media in practical engineering. |
