Long Wave and Short Wave Oscillatory Patterns in Rapid Directional Solidificationions of long or short wavelengths. For some operating conditions both instabilities are present at criticality; situations that lead to competition between different scales. Here we focus on the instabilities of Hopf type; combining nonequilibrium thermodynamics, thermal effects and weak flows in di

A Note on the Stability of a Solidifying Material in an Under-Cooled Melt in the Presence of Convectsurface tension is not very small or if the under-cooling is very small. A surprise of sorts turns up when gravity is reversed and the liquid melt acts like it is heated from above for here the perturbed convective fields destabilize the interface further moving the critical wavelengths to smaller v

Simulation of Natural Convection Effects on Dendritic Growthnvection past a crystal growing from a nucleus on a solid wall has been studied in Tönhardt & Amberg (1998), Tönhardt & Amberg (2000a)..In the present contribution (see Tönhardt & Amberg (2000b) for a full account), a numerical study of the effect of natural convection on the growth of SCN crystals

Measurements of Liquid Diffusion Coefficients in Transparent Model Systemsface energies and liquid diffusion coefficients are probably the most difficult quantities to determine precisely: this contribution raises some questions about the latter..The question arising is whether values of . . derived from solidification (or melting) analyses should be expected to give the

Interfaces on All Scalesor follow almost perfectly the plane of a crystalline lattice. Somewhat paradoxically, on the scale of millimeters or centimeters, the molecularly rough interfaces appear smooth, while the relaxed interfaces are facetted, with angular edges. Locally planar solid-liquid interfaces can be morphologica
