| Abstract: | Due to the influence of turbulence flow effect and near-wall treatments on the results of inertance tube,the previous models based on 1-D and small pressure ratio have a poor agreement with the experimental dates.The Pulsatile turbulent flow in inertance tube was numerically modeled using the Reynolds-averaged Navier-Stokes equation approach.The commercially available computational fluid dynamics code(CFD),FLUENT,was used for these studies.A two-dimensional mathematical model of inertance tube and reservoir... |
