Laminar-Turbulent Patterning in Transitional Flows

Wall-bounded flows experience a transition to turbulence characterized by the coexistence of laminar and turbulent domains in some range of Reynolds number R, the natural control parameter. This transitional regime takes place between an upper threshold Rt above which turbulence is uniform (featureless) and a lower threshold Rg below which any form of turbulence decays, possibly at the end of o...

Numerical Methods to Simulate Turbulent Dispersed Flows in Complex Geometries

Population Balance is a prominent ingredient of modeling transport phenomena. Population Balance Equations (PBEs) are coupled to Computational Fluid Dynamics (CFD) to simulate turbulent dispersed flows. One of the arising challenges is to obtain an appropriate discretization technique for the internal coordinate of PBEs, so the resulting equations can lead to acceptable solutions with affordabl...

Numerical Methods for Solving Turbulent Flows by Using Parallel Technologies

Parallel implementation of algorithm of numerical solution of Navier-Stokes equations for large eddy simulation (LES) of turbulence is presented in this research. The Dynamic Smagorinsky model is applied for sub-grid simulation of turbulence. The numerical algorithm was worked out using a scheme of splitting on physical parameters. At the first stage it is supposed that carrying over movement a...
