Numerical Implementation of Boundary Conditions on Bubbles in a Microchannel with Stationary Laminar Flow
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.
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.
