Study on the Numerical Simulation of the Contamination of Batching Transportation of Products Oil with Turbulent Theory

A comparative analysis on current contamination theory is made and establishes 3D unsteady contamination turbulent numerical calculation model based on the mass and momentum transfer coupling. Further-more, on the basis of PHOENICS 3. 6 software, the PLANT mode is programmed and q1 document on numerical simulation of contamination is set up. The calculation and analysis on the concentration diffusion of batch transporting # 0 diesel and # 90 gasoline in perpendicularly up and down pipeline and concentration field of different transportation batches are made.
