gradient of a scalar always being equal to zero. In the case of an incompressible flow the velocity potential satisfies Laplace's equation, and potential...

Gromeka–Arnold–Beltrami–Childress (GABC) flow is a three-dimensional incompressible velocity field which is an exact solution of Euler's equation. Its representation...

⋅ F = 0 {\displaystyle \nabla \cdot \mathbf {F} =0} such as for an incompressible fluid or a magnetic field, the identity ∇ × ( ∇ × F ) ≡ − ∇ 2 F + ∇...

on function theory is that u represents a velocity potential of an incompressible steady fluid flow in the plane, and v is its stream function. Suppose...
