Hi all;
what's the difference between icoFoam and simpleFoam run with turbulence model?

Thank you!

icoFoam: Transient solver for incompressible, laminar flow of Newtonian fluids.
simpleFoam: Steady-state solver for incompressible, turbulent flow
pisoFoam: Transient solver for incompressible flow.
Turbulence modelling is generic, i.e. laminar, RAS or LES may be selected.

look in source, you can find description for each solver!
if you compare them, you will find little differences
for examples:
in simpleFoam
in momentum equation fvm::ddt(U) is omited because it solves for steady-state
or
in icoFoam friction term is like that fvm::laplacian(nu, U) which does not count turbulence effect
