Pressure, no viscous stress is selected, also enter a Reference velocity scale Uref (SI unit: m/s).

•If Specify turbulence variables is selected, enter a value for the Turbulent kinetic energy k0 (SI unit: m2/s2) and Turbulent dissipation rate 0 (SI unit: m2/s3).

Select an option from the Dispersed phase boundary condition list—No dispersed phase

flux (the default), Dispersed phase concentration, Dispersed phase outlet, Disperse phase

flux, or Symmetry.

•If Dispersed phase concentration is selected, enter a Dispersed phase volume fraction

d0 (unitless). For The Mixture Model, Laminar Flow Interface also select Dispersed phase number density to enter a value for n0 (SI unit: 1/m3) or Diameter of particles/ droplets to enter a value for dd (SI unit: m).

•If Disperse phase flux is selected, enter a Disperse phase flux d (SI unit: m/s). For

The Mixture Model, Laminar Flow Interface also enter a Number density flux n

(SI unit: 1/(m2 s)).

Outlet

The Outlet feature adds a selection of boundary conditions that describe the outlets in a fluid-flow simulation; that is, the conditions at boundaries where the fluid exits the domain. Select Velocity, Pressure, no viscous stress (the default), or No viscous stress for outlet boundaries.

All of the formulations for the Outlet type are also available, possibly slightly modified, in other boundary types as well. This means that there is nothing in the mathematical formulations that prevents a fluid from

Note entering the domain through boundaries where the Outflow boundary type is specified.
