Source and Multimedia Environmental Behavior of PAHs in Dalian Urban Area;

In view of the question of pollution of persistent organic pollutants(POPs),the environment end-result simulating system of regional environment's persistent organic pollutants oriented is studied and developed,which uses the hot spot model of the environment end-result simulating technology——multi-medium fugacity model and the computer software technology.

An Application and Study of Level Set Method in Multi-material Flows;

When the compressible multi-material flows are numerically simulated,much trouble is made from two different state equations.

The level set method based on adaptive Cartesian grids is used to simulate multi-material flow problems.

Numerical methods based on unstructural moving grids are developed to solve compressible multi-material flows where an arbitrarily moving interface exists between two immiscible fluids.
