Description

IMPERMEABLE

No gas or solids flow through the surface.

SEMIPERMEABLE

Gas flows through the surface with an additional resistance. Solids velocity through the surface is set to zero or to a user- specified fixed value (i.e., solids momentum equation for this direction is not solved).

8.3.11.14. IS_PC(IS, IDX)

Data Type: DOUBLE PRECISION

  • \(1 \le IS \le 500\)

  • \(1 \le IDX \le 2\)

Parameters defining the internal surface. These values need to be specified for semipermeable surfaces only. The thickness used for pressure drop computation is that of the momentum cell (DX_e, DY_n, or DZ_t). To turn off the resistance, use a large value for permeability.

  • IDX=1: Permeability [1.0E32]

  • IDX=2: Inertial resistance coefficient [0.0]

8.3.11.15. IS_VEL_S(IS, PHASE)

Data Type: DOUBLE PRECISION

  • \(1 \le IS \le 500\)

  • \(1 \le Phase \le 10\)

Value of fixed solids velocity through semipermeable surfaces.
