Abstract:
The water flow field in automatic screen filter with torpedo was numerically simulated at different flow rates via the porous jump model and Realizable k-ε model in FLUENT. The results showed that the calculated head loss was highly consistent with the test result. Thus, the mathematical model was highly accurate and reliable. The comparison among the calculation results at different flow rates showed that the velocity and pressure distribution patterns were the same at different flow rates within the filter. The greater the flow, the greater the head loss, and the greater the velocity and pressure difference between the inner and outer sides of the screen. The velocity and pressure distribution were not uniform in the filter. Therefore, the structure of the filter awaits further optimization.
