Inviscid flow
Summary
An inviscid flow is a flow of a fluid with zero viscosity, so that the only internal force is pressure. Its motion is governed by the Euler equations. Real fluids are viscous. But at high Reynolds number the flow away from walls and wakes is close to inviscid. This makes the idealisation the basis of classical aerodynamics and wave theory.
