Default effective? turbulent? laminar? viscosity
Posts: n/a
Guys, I have got two stupid questions for you 1) In the famous drag-particle reynoulds number: Cd=Rep/24(1+0.15*Rep^2/3); for which Rep=dp*Ur*rho/mu; now my question is, to determine the particle Reynoulds number, what type of fluid viscosity do I have to use (effective? turbulent? laminar? viscosity?) 2) In the Saffman Lift Force, there is a viscosity (or kinematice viscosity),what type of viscosity do I have to use here (effective? turbulent? laminar? viscosity?)

I think you have to use laminar viscosity.
