Adiabatic waves along interfacial layers near the critical point
arXiv:0801.2311 · doi:10.1016/j.crme.2004.01.007
Abstract
Near the critical point, isothermal interfacial zones are investigated starting from a non-local density of energy. From the equations of motion of thermocapillary fluids, we point out a new kind of adiabatic waves propagating along the interfacial layers. The waves are associated with the second derivatives of densities and propagate with a celerity depending on the proximity of the critical point.
