In the first step, 3D simulation of the system from a high pressure tank to the filter inlet is performed and the output is used as the input of second step. In the second step, simulation is performed for filters with inlet mass flow rates calculated from the previous step. To validate the model, the results are compared to experimental data showing acceptable agreement. The results show that regardless of the valve type, the cleaning pulse generates after 0.5 s and suddenly decreases afterward. No shock or choking is observed in the system. Another interesting result is the induced flow, generated after the nozzles, which increases the filter inlet mass flow rate. In addition, the axial distribution of the filter outlet flow is not uniform, degrading from inlet to outlet. Finally, a complete parametric study is performed to investigate the effect of the tank pressure on the pressure difference in the filter which is an important index in the cleaning performance analysis.
