1.谁是引发油舱爆炸的元凶许多惨训表明,大多数装载重质油品的油船油舱爆炸均是在油舱卸油快完、进行扫舱过程中发生的。究其因,引起爆炸的元凶是谁呢?须知,装载重质油品油船油舱底部都安装有蒸气管给原油重油等加温,目的是增大其流动性,便于卸油。然而,随着油温的升高,会加快重质油品中轻质镏份的挥发而增大油舱空间的油气浓度,在快速卸油时,冲入油舱的空气紊流作用. 相似文献

A simulation of the movement of spilled oil after the incident of the Russian tanker Nakhodka in the Sea of Japan, in January 1997, was performed by a particle tracking model incorporating advection by currents, random
diffusion, the buoyancy effect, the parameterization of oil evaporation, biodegradation, and beaching. The currents advecting
spilled oil were defined by surface wind drift superposed on the three-dimensional ocean currents obtained by the Geophysical
Fluid Dynamics Laboratory modular ocean model (GFDL MOM), which was forced by the climatological monthly mean meteorological
data, or by the European Center for Medium Range Weather Forecasts (ECMWF) daily meteorological data, and assimilated sea
surface topography detected by satellite altimeter. A number of experiments with different parameters and situations showed
that the wide geographical spread of oil observed is not explained by wind drift alone, and that including the simulated climatological
currents gives better results. The combination of surface wind drift and daily ocean currents shows the best agreement between
the model and observations except in some coastal areas. The daily meteorological effect on the ocean circulation model results
in a stronger variability of currents that closely simulates some features of the nonlinear large-scale horizontal turbulent
diffusion of oil. The effect of different parameterizations for the size distribution of model oil particles is discussed.
