A Numerical Simulation of Swirling Gas-solid Flow in a Vertical Pipeline
A numerical prediction for axial and swirling gas-solid flows in a vertical pipe was carried out with an Eulerian approach for the gas and a stochastic Lagrangian approach for particles, where particle-particle and particle-wall collisions were taken into consideration. The kε turbulence model was used to characterize the time and length scales of the gas-phase turbulence. Models predicting the...
متن کاملCoupling Between a Viscoelastic Gas/Liquid Interface and a Swirling Vortex Flow
While the structure and dynamics of boundary layers on rigid no-slip walls in rotation dominated enclosed flows are still an area of active research, the interactions between rotating or swirling flows with a free surface have received comparatively less attention. For the most part, investigations in this area have been focused on clean free surfaces, which may be treated as stress-free. Howev...
متن کاملThe unstable spectrum of swirling gas flows
The asymptotic structure of the discrete spectrum of a compressible inviscid swirling flow with arbitrary radial distributions of density, pressure and velocity is described for disturbances with large wavenumbers. It is shown that discrete eigenmodes are unstable when a criterion derived by Eckhoff & Storesletten (1978) is satisfied. In general, these modes are characterized by a length scale ...
