7.2: Vortex dynamics in a homogeneous, inviscid fluid
2022年7月23日 · In an inviscid, homogeneous fluid, vortex filaments move with the flow. One may say that vortex filaments are “frozen” into the flow. Remember that the time derivative of the separation vector can also be written in terms of the the strain rate and rotation tensors (cf. …

Inviscid flow - Wikipedia
In a 1757 publication, Leonhard Euler described a set of equations governing inviscid flow:
Assuming inviscid flow allows the Euler equation to be applied to flows in which viscous forces are insignificant. Some examples include flow around an airplane wing, upstream flow around bridge supports in a river, and ocean currents.Wikipedia · CC-BY-SA 许可下的文字- Suppose that in the equations of vorticity under the hypothesis that the external forces derive from a potential, which means in we set then we get For a barotropic fluid (obviously for an incompressible fluid too) be-cause and taking into account the equation of conti-nuity, it turns out that so that we obtain Similarly, from we get such that, for...
Irrotational Vortex (Free Vortex) A free or potential vortex is a flow with circular paths around a central point such that the velocity distribution still satisfies the irrotational condition (i.e. the …
