Numerical Simulation on Flow Field of Screen Filter for Drip Irrigation in Field

Abstract:

Based on CFD software Fluent, the flow field of screen filter was simulated numerically，and the results of calculation were analyzed in detailed. The results show that the velocity distribution declines along the radial direction of tank. The flow can be rotated and mixed in tank, and the screen of outlet can be clogged quickly resulting in uneven clogging. The turbulent pressure distribution of filter is not uniformity. In the inlet, the turbulent energy is larger than the second tank. In the inlet of second screen, there is a high turbulence region resulting in the larger head loss. The pressure distribution of the second tank is uniformity in the course of filter work. However, the pressure of the first tank is significantly higher than the second one.
