Abstract EN
The smoothed particle hydrodynamics (SPH) method is applied to study the oil film diffusion in the water.
By modifying the SPH equations of fluid dynamics, the multiphase flow SPH equations are obtained to establish the computational oil film diffusion model.
By discussing three kinds of particle pairing schemes in the calculation of oil particle density, the redistribution mode of particle density is determined.
The diffusion process of oil film is simulated, the effects of oil viscosity coefficient and particle density on oil film diffusion are analyzed, and the distribution of local pressure near oil particles in the process of oil film spreading is calculated.
Finally, the calculated value of the oil film expansion diameter is compared with two other numerical models, and the calculated result shows a high coherence with the others.
