If you have chosen constant settling velocity you must specify the value as either a constant or a type3 file.
If you have chosen to include flocculation:
For the part below cfloc the formulation is:
(4.1)
For the part between cfloc and chindered the formulation is:
(4.2)
For the part above chindered the formulation is:
(4.3)
If hindered settling is applied, the formulations of Richardson and Zaki are available (see reference manual).
You must specify the following parameters:
Gelling point (cgel): |
The point for which the settling velocity is negligible |
Density of sediment: |
(r saliment) Density of the sediment |
Concentration for hindered settling: (chindered) The minimum concentration for which hindered settling occurs.
Concentration for flocculation: (cfloc) The minimum concentration for which flocculation occurs.
g is set to 1.
Wsn is set to 1.
