Numerical Analysis Method For The Traffic Pollution Pool

In order to keep the social economy to develop sustainably, it is important that the runoff of highway surface is analyzed, and it is therefore harnessed efficiently. To conduct the fluent environment analysis, an important basic work is to analyze the hydrodynamics behaviour and pollution situation of the water body based on hydrodynamics. This paper makes a fluent environment for the highway from Zengcheng to Conghua and established the control system to simulate the pollution pool. It is the rock poolâ†'the adsorption poolâ†'the chemical reaction poolâ†'natural pool or biochemical pool.In this paper,according to the related knowledge of fluent hydrodynamics and the contaminant, Navier-Stokes equation and convection-diffusion equation are used. Further more, this paper mainly discussed the two-dimensional model, it focused on the SIMPLE algorithm to simulate the fluent environment and the least square method to get the convection-diffusion coefficient. Next, by the FLUENT software to simulate and get the chart of concentration, we compared the different models to find the optimization results. Finally, the examples are given to illustrate the simulate algorithm to be valid for analysis of traffic pollution pool.
