A combined analytical, numerical, and experimental study of the traveling-wave wall mode in rotating Rayleigh-Bénard convection is presented. No-slip top and bottom boundary conditions are used for the numerical computation of the linear stability, and the coefficients of the linear complex Ginzburg-Landau equation are then computed for various rotation(More)
The feasibility of using an industrial compressible CFD code for large eddy simulations (LES) is evaluated. Dynamic subgrid scale (SGS) models developed at CTR have been implemented into the code and tested in a fully developed turbulent channel flow. In order to evaluate the effects of the SGS model compared with the numerical dissipation inherent in the(More)
An experimental and theoretical study is carried out of the flow of granular material in cylinders with different cross-sectional shapes rotated about their axes. The flow of particles in such geometries is confined to a shallow layer at the free surface. The length and thickness of the layer shrink and expand periodically with rotation of the cylinder,(More)
The present research is comprised of theoretical investigations of three problems in the mechanics of internal waves of large amplitude, using analysis and numerical methods. In the first problem, the flow of a Boussinesq density-stratified fluid of large depth past the algebraic mountain ('Witch of Agnesi') is studied in the hydrostatic limit using the(More)
