Abstract: A three-dimensional entity model and its flow field model are established for a four-layer sintered metal mesh of the filter screen by adopting CFD software. The filter screen is numerically simulated according to the different filtering velocities of the filter screen. The simulation results are compared with the experimental results to obtain the fitting calculation equation and analyze the internal flow field characteristics of the filter screen. It shows that the difference between the simulation results and the experimental results is not significant, confirming the reliability of the method for the filter simulation. It can provide reference for the performance analysis, the prediction and the design of the filter screen.
