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(Rei) 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°.
