Large Eddy Simulation of reverse-flow centrifugal separators
نویسندگان
چکیده
Different CFD models of reverse-flow centrifugal separators namely swirl tubes have been built in order to study and detail analysis of the phenomenon of the "end of the vortex". The present work based on previous experience and experimental activities in the field of this phenomenon. The models was built in absolutely agree with geometrical characteristics and operating conditions of experimental works [1, 2]. Two different types of swirl tubes were analyzed. One in principle long tube with varied length was study to visualize behavior of the vortex core depending to the total length of separator. Other was built to improve the influence of so-called collection vessel and its depth on the phenomenon of "vortex end". Simulations were carried out using commercial CFD package Star-CD. Obtained results are qualitatively agreed with earlier obtained experimental data [2].

Large Eddy Simulation of the vortex end in reverse-flow centrifugal separators
The present work is a study of the gas-flow phenomenon known as the ?end of the vortex? (EoV), which spontaneously occurs at the lower end, or under, reverse-flow centrifugal separators such as cyclones or swirl tubes. Different CFD models of swirl tubes have been built to study and analyse this phenomenon in detail. The present numerical work is based on ? and compared with ? previous experime...

Large-eddy simulation of turbulent flow over an array of wall-mounted cubes submerged in an emulated atmospheric boundary-layer
Turbulent flow over an array of wall-mounted cubic obstacles has been numerically investigated using large-eddy simulation. The simulations have been performed using high-performance computations with local cluster systems. The array of cubes are fully submerged in a simulated deep rough-wall atmospheric boundary-layer with high turbulence intensity characteristics of environmental turbulent fl...

In this study, turbulent flow around a tube bundle in non-orthogonal grid is simulated using the Large Eddy Simulation (LES) technique and parallelization of fully coupled Navier – Stokes (NS) equations. To model the small eddies, the Smagorinsky and a mixed model was used. This model represents the effect of dissipation and the grid-scale and subgrid-scale interactions. The fully coupled NS eq...
