静水环境中不同泄漏条件下水下溢油扩散实验研究
Experimental Study on the Diffusion of Underwater Oil Spills Under Different Release Conditions in Static Water Environment
摘要
Abstract
Based on a self-made small-scale vertical water tank with dimensions of 0.5 m × 0.5 m× 1.0 m(length × width × depth),this article conducts physical simulation experiments on underwater oil spills using DAS BLEND crude oil as the simulated pollutant.This study examines the effects of release conditions,including three types of spill orifice diameters(1.0,1.5,and 2.0 mm)and four initial injection velocities(characterized by the pump's revolutions per minute,at 40,60,80,and 100 r/min),on the transport and diffusion of underwater oil spills.The indicators for assessment include the diffusion range,particle quantity distribution,particle size distribution,cumulative volume distribution,and median particle size of oil droplets.The experimental results show that,in the static water environment,the underwater oil spill primarily transports and diffuses along the vertical centerline of the orifice to the water surface.The diffusion range of oil droplets decreases with the increase in orifice diameter;the quantity of oil droplets decreases with the increase in orifice diameter but increases with the increase in injection velocity.The particle size distribution of oil droplets generally follows a normal distribution,with a larger orifice diameter leading to a broader range of oil droplet sizes.The median particle size of oil droplets becomes smaller as the injection velocity increases.The findings of this study can provide a useful reference for the improvement of related physical experiments and numerical models in the future.关键词
