Inhaltsangabe

The phase transformation from liquid to solid is a phenomenon central to a wide range of manufacturing and natural processes. The presence of phase transformation can drive convection in the melt through the liberation of latent heat, the rejection of solute, and the change of density upon freezing. The fluid mechanics itself can playa central role; the phase transformation can be strongly altered by convective transport in the liquid through the modification of the thermal and solutal environment of the solid-liquid interface; these local fields control the freezing characteristics at the interface. The convection can be generated naturally by buoyancy forces arising from gradients of temperature and concentration in the liquid, by density changes upon freezing, and by thermocapillary and solutocapillary forces on liquid-solid interfaces. The interactive coupling between solidification and convection forms the subject of this volume. Such coupled processes are significant on a large range of scales. Among the applications of interest are the manufacture of single crystals, the processing of surfaces using laser or molecular beams, and the processes of soldering and welding. One wants to understand and predict macrosegregation in castings, transport and fractionation in geological and geophysical systems, and heat accumulation in energy redistribution and storage systems. This volume contains papers presented at the NATO Advanced Research Workshop on "Interactive Dynamics of Convection and Solidification" held in Chamonix, France, March 8-13, 1992.

Reseña del editor

The phase transformation from liquid to solid is often tightly coupled with convective transport in the melt. Such coupled processes are significant on a broad range of scales. Interactive Dynamics of Convection and Solidification gives the first overview of the field as a whole. Both theoretical and experimental studies provide a fundamental understanding of the physical mechanisms involved. On the microscale, there are discussions of morphological instabilities, their finite-amplitude evolutions, and the development of cells and dendrites. On the mesoscale, there are discussions of `developed' cells and dendrites, and of mushy zones. On the macroscale, there are discussions of full `systems' of solidifying/melting and convecting material. Here the influence of flow on crystal-growing processes, processing by beams, spin casting, macrosegregation in casting and geological systems, and energy conversion in engineering systems are all discussed.
