应用VOF方法对水流中拦油栅拦油失效进行数值模拟尝试

通过自编程和流体体积分数法模拟计算了两种拦油失效的情形；低粘度的油类在水流速度超过某一临界值时发生了油滴夹带失效；粘度很大的油类在水流速度超过临界值时发生了临界累积失效，模拟结果在定性上与已有的实践结果相一致。

Preliminary numericalsi mulation of boom failure with VOF model

Floating boomshave been com monly used to contain spilled oilon watersurface,whilefailure often occursincurrents with highvelocity.Inordertostudyboom failure mechanisms,ComputationalFlu id Dynamics methods have been used by now .As a preliminary application of volume offluid (VOF) modelinself compiled SIMPLEprogram ,twocasesofoilfailure weresimulated:whencriticalcurrentve locityisexceeded,dropletentrainment occursforlow viscosity oil while critical accumulation occurs for high viscosity oil.In the computation,fluid flow is simplified to be laminar.The simulation results are qualitativelyidentical withexperimentandthesimulationresultsobtained by Dr.C.
