Sentence examples for minimum bubbling velocities from inspiring English sources
A carefully formulated strategy is presented for establishing the minimum fluidization and minimum bubbling velocities by DEM simulations.
The minimum fluidization and minimum bubbling velocities were obtained for various field intensities, enabling determination of the boundary between Group B and A behaviour.
We find that the minimum bubbling velocities as obtained from the simulations are in reasonable agreement with the well-known experimental correlation of Abrahamsen and Geldart (Powder Technology, 1980, 26: 35–46).
Mesh size has a drastic effect on minimum bubbling velocity.
When the velocity of a gas through a bubbling fluidized bed is increased above the minimum bubbling velocity, the bubble size increases and frequently split and coalesce passing through the bed as slug.
Omitting frictional stress or changing no-slip to free-slip boundary condition for gas phase had the effect of delaying minimum bubbling velocity.
Review of several simulations across all the mesh sizes studied, revealed the presence of persisting dilute regions getting triggered around experimental minimum bubbling velocity.
Most notable of these characteristics is the existence of non-bubbling fluidization for a range of gas velocities between the minimum fluidization velocity and the minimum bubbling velocity.
The minimum fluidization velocity (Umf) and the minimum bubbling velocity (Umb) of the powders studied were determined in a cylindrical fluidized bed.
Furthermore, we have performed a systematic investigation into the effect of the specific method that is used for determining minimum bubbling velocity.
Properties of the micro-fluid bed such as the minimum fluidization velocity (Umf), the minimum bubbling velocity (Umb), bed expansion, and identification of the fluidization regime are investigated by visual inspection.
