2-DIMENSIONAL NUMERICAL CALCULATION OF FLOW AND MIXING USING THE CIP METHOD

摘要

Numerical models are useful to predict the characteristics of environmental systems at the interface between waters of different densities. In the last few years, some models have been proposed to calculate factors including flow in stratified and closed water systems and saltwedges. They provided favorable results. Models that analyze the flow of waters of different densities are needed to accurately calculate density distribution. However, models that take an ordinary finite differential method suffer from a major difficulty in calculating the advection term because numerical diffusion. In this paper, a simple two-dimensional numerical model is constructed. The model uses the CIP method in the calculation of advection term, in order to calculate density flows more accurately without using complicated models. The model applicability was verified by the comparison between the calculation and the experimental results under the same condition.
