摘要
The concentration distribution of oiled wastewater under the water surface in a two-dimensional open channel was studied by means of experimental and numerical method. The experiments were carried out under nine different working conditions, which were formed by changing the discharge condition in the open channel and ratio of oil to water in oiled wastewater. The flow field and oil concentration field for each working condition were measured and solved numerically by using the k-2 turbulence model. The comparison of numerical results with measured data shows good conformity. The diffusion coefficient of the oiled wastewater in vertical direction was obtained. The distribution of oil concentration and diffusion coefficient was also discussed.
