Abstract

This article presents a method of collaborative one-dimensional (1D)–three-dimensional (3D) modeling of computational fluid dynamics. The method is based on the simultaneous calculation of 3D and 1D areas and linking the two parts of the problem by transferring the boundary conditions. The 3D approximation region is modeled based on the solution of Navier-Stokes equations. The 1D regions are calculated using the basic conservation laws and the empirical characteristics of elements. The proposed solutions are validated through several tasks. For each task, the results are compared with the available analytical solutions or the experimental data.

一维和三维计算流体动力学问题的协同计算方法

摘要

本文介绍了一种计算流体动力学的协作一维（1D）-三维（3D）建模方法。该方法基于同时计算3D和1D区域，并通过传递边界条件将问题的两个部分联系起来。基于Navier-Stokes方程的解对3D近似区域进行建模。一维区域是使用基本的守恒定律和元素的经验特性来计算的。所提出的解决方案通过几个任务进行了验证。对于每个任务，将结果与可用的分析解决方案或实验数据进行比较。
