Earlier attempts to describe surface gravity waves using potential flow were made by, among others, Gerstner derived a nonlinear trochoidal wave theory in 1802, which however is not irrotational.

Physically, this contradiction is removed by the formation of a shock wave, a tangential discontinuity or a weak discontinuity and can result in non-potential flow, violating the initial assumptions.
43.
The governing equation of Hele-Shaw flows is identical to that of the inviscid potential flow and to the flow of fluid through a porous medium ( Darcy's law ).
44.
The right hand side contains ( as a factor ) the simple second-power law from potential flow theory, applied at the trailing edge near \ zeta = + 1.
45.
In particular, simple potential flows ( called elementary flows ) such as the free vortex and the superposed to create more complex flows satisfying a variety of boundary conditions.
46.
In flow regions where vorticity is known to be important, such as wakes and boundary layers, potential flow theory is not able to provide reasonable predictions of the flow.
47.
According to Thouret's study of the geological evidence, at least 220, 000 people in Arequipa are at risk from potential flows of rock and volcanic debris, mudslides and flash floods.
48.
Based on the analysis of the full nonlinear problem of surface gravity waves within potential flow theory, the above cnoidal waves can be considered the lowest-order term in a perturbation series.
49.
For instance, in computational fluid dynamics, one technique is to couple a potential flow solution outside the boundary layer to a solution of the boundary layer equations inside the boundary layer.

Even though North Africa only has 15 funds for investors, versus 200 devoted to Latin America, " the potential flow of funds from local and foreign sources can be significantly higher ."
