Numerical Simulation of Turbulent Subsonic Compressible Flow through Rectangular Microchannel
In this study, turbulent compressible gas flow in a rectangular micro-channel is numerically investigated. The gas flow assumed to be in the subsonic regime up to Mach number about 0.7. Five low and high Reynolds number RANS turbulence models are used for modeling the turbulent flow. Two types of mesh are generated depending on the employed turbulence model. The computations are performed for R...
متن کاملStatistical modeling of compressible turbulent channel flow
Several questions that are relevant to turbulence modeling are addressed on the basis of recently obtained direct numerical simulation results of turbulent supersonic channel flow. In particular, this concerns the turbulence frequency production mechanism, wall damping effects on turbulence model parameters, and the relevance of compressibility effects. Limited support is found for usually appl...
متن کاملSimultaneous estimation of heat fluxes applied to the wall of a channel with turbulent flow using inverse analysis
The main purpose of this study is to estimate the step heat fluxes applied to the wall of a two-dimensional symmetric channel with turbulent flow. For inverse analysis, conjugate gradient method with adjoint problem is used. In order to calculate the flow field, two equation model is used. In this study, adjoint problem is developed to conduct an inverse analysis of heat transfer in a channel...
متن کاملLarge Eddy Simulation of Compressible Turbulent Channel Flow with Spectral Difference method
This paper presents the development of a three-dimensional high-order solver with unstructured spectral difference method. The solver employs the formulations of Sun et al. It is implemented on unstructured hexahedral grid elements. It is firstly validated using test problems of 2D and 3D subsonic inviscid flows past a circular cylinder. The spectral difference method constructs element-wise co...
متن کاملNumerical 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...
