TY - JOUR TI - Numerical simulation method of marine oil-water separation AU - Li Yunfeng AU - Li Yuting JN - Thermal Science PY - 2021 VL - 25 IS - 6 SP - 4035 EP - 4042 PT - Article AB - In order to reduce the frequency of marine environmental pollution accidents, marine oil-water separation numerical simulation method is developed. The oil-water separation hydrocyclone is used for emergency treatment to deal with the marine surface oil pollution, and the oil-water separation optimal control parameter calculation method based on the mathematical model of the flow field is used to simulate the oil-water separation performance of the device. The simulation results show that when the split ratio is 4.1%, the inlet pressure is 0.15MPa, the overflow pipe diameter is 3 mm, the oil droplet size is 101, and the large vertebral angle is 27, the hydrocyclone has good separation performance. Under these conditions, this method can be used as a reference method for dealing with oil spills in the ocean and has certain application value.
