Then, combined with several traditional solid-liquid flow models, the dynamic model was solved by the CFD software FLUENT 14.5 to simulate the influences of flow rate and hydrate volume fraction on pipeline hydrate slurry flow behavior in oil-water systems.
Then gas-solid two-phase flow model and the k-ɛ turbulent model are selected to simulate the flow of metal powder in powder nozzle.
Based on the observed physical features of the solids flow, these RTDs were modeled using a two-zone one-dimensional cross-flow multistage stirred reactors (CFMSR) model.
The residence time is calculated using solid flow or liquid flow model, depending on the degree of decrosslinking.
In an effort to figure out the causes of reamer blade balling which occurs during the process of hole enlargement while drilling, a solid-liquid two-phase flow model was built to simulate the cutting movement, and analysis was done on the simulation data.
In this paper a mathematical model for solids flow in gas flowing solids fixed bed contactors is developed.
In contrast, the field model forecast by the steady flow model (black solid line) is poorest at degree 3 (coefficients and ), but better at degrees 1, 2 and 4 6.
On the other, it is related to the way frictional solid stress was modeled: we employed the kinetic theory of granular flow model for the frictional solid pressure and the model of Schaeffer (1987) for the frictional solid viscosity.
The results showed that the solids flow could be described by the dispersed plug flow model.
Various models were tested to characterize the non-ideal solids flow patterns within the fluid bed.
A theoretical model was derived based on momentum balance equation and used to predict the solids flow rate.
