Fluid flow which is not subjected to direct influence of the fluid viscosity (except for the indirect influence of contact forces, see below).
In this case Navier-Stokes fluid flow momentum equation simplifies to Eauler fluid flow momentum equation.

This flow regime happens for high Reynolds numbers
, which originates from: LaTeX Math Inline body {\rm Re} \gg 1
low-viscosity fluids | high velocities
| large distance to solid boundaries restricting the flow
|
The Reynolds numbers should not necessarily to be very high to induce an inviscid flow and many a laminar flows
