摘要

本文采用基于Comsol Multiphysics 5.6软件包的v2-f模型和双流体湍流模型，对急剧膨胀的高旋涡流场进行了数值研究。所得结果与已知不同管径下的实验数据进行了比较。这项工作的目的是测试模型描述各向异性湍流的能力。结果表明，双流体模型更适合于此类流动的研究。

Comparison of the Results for Calculation of Vortex Currents After Sudden Expansion of the Pipe with Different Diameters

Abstract In this work, a numerical study of a sharply expanding highly swirling flow is carried out using v2-f models based on the Comsol Multiphysics 5.6 software package and a two-fluid turbulence model. The results obtained are compared with known experimental data with different pipe diameters. The purpose of this work is to test the ability of models to describe anisotropic turbulence. It is shown that the two-fluid model is more suitable for studying such flows.
