【 摘 要 】

A modern CFD code was used to simulate fluid flow through a pipeline with an orifice. A two-dimensional flow was assumed. The influence of the turbulence model and the size of the numerical grid on the quality of the obtained results was tested. It appears from the performed calculations that the standard Launder-Spalding k-ε model yields the best results for two-dimensional flows through pipeline-orifice systems.
