Summary
Landau's Two-Fluid Model
describes
Superfluid helium
as a mixture of two interpenetrating fluids: a
Normal Fluid Component
that carries
Entropy and heat
, and a
Superfluid Component
that flows without viscosity or
Thermal Resistance
. This groundbreaking model captures the
Peculiar behaviors of superfluidity
, including
Frictionless Flow
and
Quantized Vortices
, by characterizing the interplay between the
Two distinct fluid phases
.
