12.1.10. Boundary Conditions¶
Boundary conditions (BC) are specified over flow planes or 2D surfaces that are normal to one of the coordinate directions and coincide with a face of the scalar control-volume. The values for one of the three pairs of coordinates are equal. The surface is defined by the constant coordinates of each of the four edges, which can be specified with physical coordinates or cell indices, and the two equal values for the direction normal to the face, which can only be specified with physical coordinates. If cell sizes are not small enough to resolve a surface specified using physical coordinates, MFIX will indicate this problem with an error message.
A flow plane must have a wall cell (or an outside boundary) on one side and a
flow cell on the other side. The BC section is also used to specify obstacles in
the flow domain. Obstacles are 3D regions, just as for the IC regions: X_w
X_e, Y_s Y_n, and Z_t Z_b. By default the outside boundary is initialized as
no-slip walls. For cylindrical coordinates the axis is initialized as a
free-slip wall.
Two boundary surfaces must not intersect. Two obstacle regions may intersect.

Type of boundary.
Name |
Default? |
Description |
|---|---|---|
|
The specified boundary condition is ignored. This is useful for turning off some boundary conditions without having to delete them from the file. |
|
|
Mass inflow rates for gas and solids phases are specified at the boundary. |
|
|
The specified values of gas and solids mass outflow rates at the boundary are maintained, approximately. This condition should be used sparingly for minor outflows, when the bulk of the outflow is occurring through other constant pressure outflow boundaries. |
|
|
Inflow from a boundary at a specified constant pressure. To specify as the west, south, or bottom end of the computational region, add a layer of wall cells to the west, south, or bottom of the PI cells. Users need to specify all scalar quantities and velocity components. The specified values of fluid and solids velocities are only used initially as MFIX computes these values at this inlet boundary. |
|
|
Outflow to a boundary at a specified constant pressure. To specify as the west, south, or bottom end of the computational region, add a layer of wall cells to the west, south, or bottom of the PO cells. |
|
|
Velocity gradients at the wall vanish. If BC_JJ_PS is equal to 1, the Johnson-Jackson boundary condition is used for solids. A FSW is equivalent to using a PSW with Hw=0. |
|
|
All components of the velocity vanish at the wall. If BC_JJ_PS is equal to 1, the Johnson-Jackson boundary condition is used for solids. A NSW is equivalent to using a PSW with vw=0 and Hw undefined. |
|
|
Partial slip at the wall implemented as the boundary condition: dv/dn + Hw (v - vw) = 0, where n is the normal pointing from the fluid into the wall. The coefficients Hw and vw should be specified. For free-slip set Hw = 0. For no-slip leave Hw undefined (Hw=+inf) and set vw = 0. To set Hw = +inf, leave it unspecified. If BC_JJ_PS is equal to 1, the Johnson-Jackson boundary condition is used for solids. |
