Sinopsis

A few problem areas in materials science are reviewed with regard to the importance of fluid flows, in particular flow instabilities and turbulence. One class of such flows in melts are driven by surface tension gradients caused by temperature differences. These are frequently responsible for instabilities or turbulence that is often undesired in practical processes, as in crystal growth. Another area that is of obvious importance in materials processes is solidification. Fluid flows are crucial here, since the growth rate, the shape and size of the solid structures are greatly influenced by melt convection.
