Helmholtz Instability
Helmholtz Instability : Also called: shearing instabdity: The hydrodynamic instability arising from a shear, or discontinuity, in current speed at the interface between two fluids in two-dimensional motion. The perturbation gains kinetic energy at the expense of that of the basic currents. Refer to source for relevant equation(s). N.B. Refer to source to verify equation(s).
