ANSYS Fluent Simulation (cont.)
- Discrete Phase Model (DPM)
- Allows for multiple fluid and particulate phases
- Fluid phase (i.e. the cement) is modeled as a Newtonian
fluid
- Aggregate (sand) and entrained air bubbles both modeled
as inert particle injections
- Sand - 500μm diameter
- Air bubbles - 1mm diameter
