Пример численного решения уравнений Навье-Стокса методом маркеров и ячеек для моделирования водных объектов

Abstract

The example of the numerical solution of the equations of Navier-Stokes by method of the markers and cells right-hand differential approximations developed Harlow and Welch in 1965 is shown. The decision is executed in simple physical variables and isn´t consolidated to the decision in the form of variables of a whirlwind and function of current that allows to use the received decision for modeling of liquid with a free surface. It is used when modeling of water objects (lakes, the rivers, reservoirs and others). The solved differential equations describing the liquid movements are presented by nonlinear members. It does their decision to more labor-consuming, however, the received formulas allow to describe adequately circulation of the modelled liquid. On the basis of the received formulas it is possible to develop hydrodynamic models of reservoirs and to use them for modeling of transfer of heat and impurity.

Показан пример численного решения уравнений Навье-Стокса методом маркеров и ячеек правосторонними разностными аппроксимациями, разработанных Харлоу и Уэлчем в 1965 году. Решение выполнено в простых физических переменных и не сводится к решению в виде переменных вихря и функции тока, что позволяет использовать полученное решение для моделирования жидкости со свободной поверхностью. Это используется при моделировании водных объектов (озер, рек, водохранилищ и других).Решаемые дифференциальные уравнения, описывающие движения жидкости, представлены нелинейными членами. Это делает их решение более трудоемким, однако полученные формулы позволяют адекватно описывать циркуляцию моделируемой жидкости. На основании полученных формул можно разрабатывать гидродинамические модели водоемов и использовать их для моделирования переноса тепла и примесей.
