Delft3D在鳌江口外平阳咀海域流场模拟中的应用

Dem3D是以FLOW水动力模块为主体，建立在Navier-Stokes方程的基础上，由一系列模块组成的模型软件，可以对水流、波浪、泥沙、水质、地貌等建立二、三维模型。本文介绍了Delft3D数值模拟软件的程序模块及数值理论基本方程．对鳌江口外平阳咀海域的流场进行了模拟研究。研究表明：计算结果与实测结果吻合较好，能够较好地反映该海区真实的流场情况．可以为工程研究提供基本的流场背景。

Introduction of Numerical Simulation Software Dleft3D & Its Application on Offshore Area of Aojiang Estuarine

The Delft3D suite has developed a unique, fully integrated computer software suite for a multi-disciplinary approach and 3D computations for coastal, river and estuarine areas. It can carry out simulations of flows, sediment transports, morphological developments, waves, water quality, and ecology. It has been designed for experts and non-experts alike. The Delft3D software is composed of several modules basing on FLOW hydrodynamic module, grouped around a mutual interface, while being capable to interact with one another. The author describes the theoretical physics model to Delft3D-FLOW, which is based on the Navier- Stokes equations and introduces application of Delft3D on offshore area of Aojiang estuarine in this paper.
