Role of Small Computers in Two-Dimensional Flow Modeling.

Abstract

This paper describes the computational aspects and computer usage history of numerical simulations of horizontal, free surface, steady or unsteady two-dimensional flow fields. The focus is on a particular numerical model (RMA-2) that has been in use and development at the Hydrologic Engineering Center (HEC) and elsewhere for the past decade. RMA-2 solves the complete Reynold's equations for turbulent flow in two dimensions using the finite element method. Terms describing bottom friction, surface wind, and Coriolis forces are included. Details of the governing equations and solution technique are thoroughly documented elsewhere. RMA-2 may be used as a driver for sediment transport and water quality simulations as well as for computing hydrodynamic information only. Additional keywords: Computational hydraulics; Microcomputers; Bibliographics.
