Abstract In order to explore the influence of the structural parameters and installation methods of the reflective inlet component on the flow uniformity of the gravity oil-water separator and determine the optimal structural parameters, the Fluent software is adopted to numerically simulate the oil-water separator. The results show that as the jet distance d, the inflow angle θ and the vertical position of the inlet port h increase, the average uniformity of flow rate N increase first and then decrease. When d=0.075D, θ=90°, h=0.25D respectively, the maximum value of N is obtained, and the uniformity of the flow field of the bottom device is better than that of the top device. As the inflow Reynolds number(Re_i) increases, the uniformity of the flow field gradually deteriorates; the uniformity of the flow field of the bottom-mounted reflective inlet component is better than that of the down-tube box-type inlet component; the optimal value under a single parameter of the reflective inlet component is not much different from the optimization result of response surface analysis, the optimized parameters are as follows: h=0.25D, d=0.07D, θ=90°.
