Numerical Study of Cross-Flow Around Multiple Plates on a Screen

Turbulent flow in a square duct at extreme Reynolds number

Abstract Content of image described in text. We investigate pressure-driven turbulent flow in a square duct using wall-modelled large-eddy simulations (WMLES) of the Navier–Stokes equations. An equilibrium wall model based on the logarithmic law is employed, yielding results in close agreement with direct numerical sim...

Study of a system of turbulent shear layers and vortices. Part II: Reynolds-averaged turbulence modelling

Numerical Investigation of Confined Flow Around Circular and Square Obstacle Using the Multiple Relaxation Time Lattice Boltzmann

Flow behavior can be changed by parameters such as fluid properties, geometry, and operating conditions. This paper presents a 2D numerical analysis of incompressible fluid flow in a channel with either a circular or square cylinder using the multiple relaxation time Lattice Boltzmann method (LBM-MRT). All simulations...

Drag reduction and subcritical turbulence in controlled pipe flows

Abstract Content of image described in text. Pipe flow controlled by streamwise-travelling waves of azimuthal wall velocity is studied using direct numerical simulations at a bulk Reynolds number italic Re Subscript b Baseline equals 4900 Reb=4900 $\textit{Re}_b=4900$ . A comprehensive analysis of drag reduction shows...

Validity of the twin-force analogy in Couette flows

Abstract Content of image described in text. This study combines linear stability analysis (LSA) and direct numerical simulations (DNS) to investigate the coupling mechanisms of rotation, stratification and shear in two flow geometries: spanwise rotating stratified plane Couette flow (between two infinite parallel plat...
