Particle distributions in the flow over a wavy wall
In this paper we will present the results of direct numerical simulation (DNS) of the flow over a small amplitude wavy wall. The evolution in space and time of particles are released in this flow will be examined. It will be shown that small waves on the channel bottom can generate large longitudinal vortices similar to Langmuir vortices that are observed in flows with waves at the free-surface...
متن کاملEpistemic uncertainty quantification for RANS modeling of the flow over a wavy wall
While Reynolds-averaged Navier-Stokes (RANS) simulations remain the most affordable technique for simulating complex turbulent flows, the inability of linear eddy viscosity models to correctly predict flow separation and reattachment limits the reliability of the simulation outcome. A methodology to quantify the uncertainty in the simulation outcome related to the form of the turbulence model u...
متن کاملIsogeometric Variational Multiscale Large-Eddy Simulation of Fully-developed Turbulent Flow over a Wavy Wall
We report on the isogeometric residual-based variational multiscale (VMS) Large Eddy Simulation of a fully developed turbulent flow over a wavy wall. To assess the predictive capability of the VMS modeling framework, we compare its predictions against the results from direct numerical simulation (DNS) and, when available, against experimental measurements. We use C quadratic B-spline basis func...
متن کاملTurbulent Events and Gas-Side Mass Transfer Coefficients in a Wavy Air-Water Stratified Flow
Turbulence structure on the gas side of a wavy stratified flow was experimentally investigated in a near horizontal 18.7 cm (H) 10 cm (W) 5.5m (L) rectangular duct.By applying the Variable Interval Time Averaging (VITA) technique to the hot wire anemometer measurements frequency of occurrence of turbulent events were detected near the air-water interface. Experimental results showed that fr...
متن کاملInduced Dusty Flow Due to Normal Oscillation of Wavy Wall
A two-dimensional viscous dusty flow induced by normal oscillation of a wavy wall formoderately large Reynolds number is studied on the basis of boundary layer theory in the case where the thickness of the boundary layer is larger than the amplitude of the wavy wall. Solutions are obtained in terms of a series expansion with respect to small amplitude by a regular perturbation method. Graphs of...
