Numerical simulation of pulsating turbulent channel flow
Direct and large-eddy simulations of the Navier–Stokes equations are used to study the pulsating flow in a channel. The cases examined span a wide range of frequencies of the driving pressure gradient, and encompass different physical behaviors, from the quasi-Stokes flow observed at high frequencies, to a quasisteady behavior at the lowest ones. The validity of the dynamic Smagorinsky model to...
متن کاملParallel Dns Using a Compressible Turbulent Channel Flow Benchmark
In recent years, the increased use of off-the-shelf components and the large-scale adoption of parallel computing have led to a dramatic reduction in the costs associated with high-performance computing. This has enabled increased usage of compute-intensive methods, such as Direct Numerical Simulation (DNS), for the simulation of turbulent flows. We introduce a sophisticated DNS code that incor...
متن کاملTurbulent Pulsating Flow through Circular Ducts
In the present paper, a numerical method has been demonstrated which works on an overall NewtonRaphson type algorithm and is capable of solving the “inverse” problem for turbulent, fullydeveloped, pulsating pipe flows, where the mass flow rate, rather than the pressure gradient is prescribed as a periodic function of time. The momentum equation, governing the transient, fullydeveloped pulsating...

15 صفحه اولModeling of Spatial Resolution Effects Using Dns of Turbulent Channel Flow
In this study, the effect of limited spatial resolution of hot wire anemometry (HWA) is investigated through analysis of the two dimensional energy spectra from direct numerical simulation (DNS) of turbulent channel flow at Reτ ≈ 934. Various spanwise filter lengths are applied to the streamwise velocity component in order to mimic the spatial resolution of the HWA experiments. The overall effe...
