摘要
本文讨论了水流场中平流、分子扩散、湍流扩散、离散作用所引起的扩散物质质量通量的数学解析以及几种水质数学模型的应用条件。
Procedure for mathematical modeling of conversion, molecular dispersion, turbulent dispersion of pollutants in river water is studied. Mass flux of pollutant in water was analyzed. A number of water quality models were discussed based on physical models constructed by theoretical analysis. Numerical approach can be applied to find the solution of the models. The possible application of these models and the conditions for the employment were evaluated as well. To use the turbulent dispersion models for water pollution study, the consistency, validity,convergency, stability have to be considered. The flow field parameters for data input may include dispersion coefficients, initial settings, and so on.
