Thermomolecular Pressure in Surface Melting: Motivation for Frost Heave
Abstract
A thermomolecular pressure is associated with surface melting, and it can drive mass flow along an interface under a lateral temperature gradient. The pressure is a universal thermodynamic function in the limit of thick films. It may be responsible for frost heave in frozen ground.
