Study On Sloshing Effect Of Mass Transfer Between Vapor And Liquid Phases In Oil Tank Of Fishing Boats

The volatile organic compounds (VOCs) emission from the oil tank of fishing boatsduring the oil loading or fishing operations will cause a variety of hazards, such as a wasteof fuel, explosion, poison and secondary pollution.According to the literature survey, some researchers have investigated the VOCsemission with considering the oil categories, loading speeds, temperatures, pressures etc., butwithout considering the sloshing factor. In fact, during the fishing operations or refueling, theinternal fuel will slosh due to ship shakes or fuel oil momentum changes, and this sloshingmay influence the mass transfer between the liquid and vapor phases. Therefore,experimental and numerical models have been established to investigate the mass transferwith sloshing effects, namely, the behavior of the VOCs emission from the oil tank withsloshing effects.A66m long ocean squid fishing boat has been chosen as a prototype for research, andfollowing work is done in this thesis:(1) Experimental and numerical studies on the behaviorof VOCs emission in different sloshing intensity due to different loading speeds.(2)Experimental and numerical studies on the behavior of VOCs emission in different sloshingintensity due to different external sloshing intensity (ship sloshing).Finally, some results have been concluded through the experimental and numericalsimulation researches, which will be beneficial to know more about the mechanism of oilevaporative and emission, and be helpful to reduce the VOCs emission from the fishing boats.Meanwhile, this research will also be useful to reduce the VOCs emission from the othersimilar oil containers such as oil tanker, cargo and oil tank truck.
