Two-Phase Flow Modeling

We have developed two-phase modeling capability using Eulerian-Eulerian multi-phase model for gas-solid dense phase flow. This modeling approach is unsteady-state and is much time consuming when compared to diluted gas-solid flow.

Our two-phase model has been applied to the following processes:

  • Circulating Fluid Bed combustion, incorporated with heat transfer and multiple gas-solid reactions

  • Dense phase solid conveying systems of material pneumatic conveying industry

  • Aeration system design of a full-scale silo

CFD predicted dynamic particle movement in a CFD boiler using two-phase modeling. The model clearly shows the formation of a bubble and moving upward in the boiler.

CFD predicted particle injection and movement in an upward conveying riser.
