In contrast, ideal fluids can only be subjected to normal, compressive stress which is called pressure.
In an ideal fluid this energy can never be dissipated and the vortex would persist forever.
He discovered the helicity invariant in the fluid dynamics of ideal fluids in 1962.
The cycle uses two fluids in an attempt to approach an ideal working fluid.
An inviscid flow is the flow of an ideal fluid that is assumed to have no viscosity.
An ideal fluid really does not exist, but in some calculations, the assumption is justifiable.
Everything discussed here is based on the linear theory of an ideal fluid.
Boundary layer thickness is also useful in knowing when the fluid can be treated as an ideal fluid.
For an ideal fluid, Bernoulli's equation holds along streamlines.
The flow outside the boundary layer is free of shear and viscous-related forces so it is assumed to act like an ideal fluid.
