This volume contains several state-of-the art studies devoted to instabilities of melt flows in widely used crystal growth processes - Czochralski, Bridgman and floating zone. These phenomena are studied for many years and continue to attract attention nowadays when traditional crystal growth techniques are used to grow novel materials. New technological challenges initiate development of new, more powerful and more precise methods for experimental and computational modeling of crystal growth processes, some of which are described in the present articles. The stability of melt flow appeared as a challenging problem already in 1970's. Since then it motivated enormous number of studies that included also growth experiments in microgravity environment carried out on different spacecrafts. Many purely academic studies considering flows stability in rectangular or cylindrical containers were carried out keeping in mind that more realistic crystal growth configurations must be attacked in future research. Development of experimental and numerical approaches combined with the quickly developing measurement techniques and constantly increasing computer power allow the researchers to advance much more rapidly and to gather unique knowledge on computation and measurement of instabilities, understanding their physical mechanisms and control of melt flow stability. The whole topic is extremely wide and apparently cannot be covered by a volume containing several papers. At the same time the studies collected in this volume present a wide spectrum of most advances techniques and remarkable results. Being the editor of this volume I would like to express my gratefulness to all the contributors.
