Summary0004123: incompressibleDriftFlux tutorial (dahl) sludge properties not according to Brennan 2001
Descriptionsorry to bother with that, but when i was reading and comparing Brennan 2001 phd-thesis, i compared dictionary entries with values given in the phd thesis for the Dahl Experiment (page 139).
in the thesis following entries are given compared to the tutorial.

                      thesis | of tutorial
yield stress: 5.5469E-5 | BinghamCoeff 0.0005966 // one order of magnitude difference and numbers different
viscosity: 2.3143E-4 | coeff 0.00023143; // this one is correct
settling velocity: -2.198E-3 | Vc 2.241e-4; // one order of magnitude difference and numbers different

side note: in the ESI-Version, only the yield stress was different, other two values are the same like in the thesis.

so i was wondering if that is a typo or not.

Steps To Reproducecompare attached screenshot from the thesis with dictionary entries in the tutorial case.
TagsNo tags attached.

User support request.

This is just a tutorial case and runs fine as a demonstration as it is but feel free to change the properties to whatever suits your purpose.
