Abstract
Two-equation turbulent models are widely used in finite element analysis of fluid flow. The PAK program package was upgraded from the classical laminar flow to the turbulent k-omega model. The turbulence model was validated using the case of fluid flow in a backward-facing step channel. The analysis results show good agreement with experimental data reported in the literature. The code was subsequently tested on a case of fluid flow in a coronary artery bifurcation, with particular emphasis on the stenosis resulting from the patient’s disease.
