NONLINEAR INTERACTIONS IN THE FLUID MECHANICS OF HELIUM II.

Abstract

Various facets of the fluid mechanics of liquid helium are demonstrated. The governing equations are nonlinear, and hence the motion of fluids demonstrates the complexities of solution of a nonlinear field theory. In this article the liquid is considered strictly as a fluid described by a set of thermodynamic and dynamic variables interrelated by the two-fluid equations of London and Landau.
