Abstract

The paper presents the implementation of a user-defined function (UDF) for the Navier boundary condition in the Fluent software package. The study focuses on a microchannel with a laminar steady flow and a bubble structure on one of the surfaces. The influence of velocity and gradient components on the flow near the boundary is investigated. The numerical solutions obtained in a 2D formulation were verified and compared with experimental data from the literature.

静止层流微通道中气泡边界条件的数值实现

摘要本文介绍了在 Fluent 软件包中实现纳维边界条件的用户自定义函数 (UDF)。研究的重点是层流稳定流动的微通道和其中一个表面上的气泡结构。研究了速度和梯度分量对边界附近流动的影响。通过二维计算获得的数值解得到了验证，并与文献中的实验数据进行了比较。

期刊介绍： Journal of Engineering Thermophysics is an international peer reviewed journal that publishes original articles. The journal welcomes original articles on thermophysics from all countries in the English language. The journal focuses on experimental work, theory, analysis, and computational studies for better understanding of engineering and environmental aspects of thermophysics. The editorial board encourages the authors to submit papers with emphasis on new scientific aspects in experimental and visualization techniques, mathematical models of thermophysical process, energy, and environmental applications. Journal of Engineering Thermophysics covers all subject matter related to thermophysics, including heat and mass transfer, multiphase flow, conduction, radiation, combustion, thermo-gas dynamics, rarefied gas flow, environmental protection in power engineering, and many others.
