Zusammenfassung
I will deiscuss the drag of particles on granular surfaces by a fluid. I
will present simulations using FLUENT of Aeolian saltation under Earth
and Mars conditions obtaining among others the static and dynamic
threshold shear and the height of the saltation layer as function of the
wind strength.
A universal quadratic increase of the saturated flux as function of the
difference from the threshold is established.
