Abstract:
The scheme design of numerical simulation on tilt angle Aand tilt angle Bof gill2piece applied the uniform experimental design theory. With the sediment velocity on the upper surface of gill 2piece 3 as the evaluation index, velocity flow field was sim2 ulated under different tilt angles of gill2piece through the adoption of Eulerian model provided by the Fluent software. The pro2 jection pursuit regression (PPR) was used to analyze the numerical simulation results. The results showed that the influence of angle B on the effect of water 2sediment separation in the gill 2piece separation device is the highest, followed by the tilt angle A. The velocity field of gill 2piece separation device is beneficial to increase water 2 sediment separation and the effect of water 2sedi 2 ment separation is the best under the combination of A = 60b and B = 45b.
