THERMODYNAMICS OF WETTING OF SOLID-SURFACES BY MAGNETIZABLE FLUIDS

The thermodynamic behavior of deformable three phase contact systems is linked to a flow network of stream and equipotential surfaces, and the system is shown to satisfy the Bernoulli equation. In 'form transformations', occuring in wetting phenomena, the pressure is an additional degree of freedom that can balance changes in interfacial energy densities. For magnetizable fluids the magnetic energy density facilitates control of the shape of the bulk fluid and of the films that may extend from it.
