Abstract

In this paper, a model in generalized curvilinear coordinate is presented to simulate 2-D horizontal flow and sediment. Governing equations of the model are discretized by control volume method, and non-staggered grids and SIMPLE algorithm are introduced to simplify the program. This model is used to simulate the movement of flow and sediment in Shashi reach of the Yangtze River, China, simulated results indicate this model can correctly reflect the movement rules of flow and sediment, which verifies the model can be applied in engineering practice.

Keywords: Generalized curvilinear coordinate; non-staggered grids; control volume method; SIMPLE algorithm
