Microgravity Fluid Mechanics

Substantial progress has been made in the field of fluidmechanics under compensated gravity effects (microgravity).The main task of this disciplinehas evolved tremendously.Starting out with the aim of providing assistance indescribing flow problems in other microgravity sciences,microgravityfluid mechanics has itself now becomeacknowledge as a powerful means of research.The IUTAM Symposium on Microgravity Fluid Mechanics has pro-vided the long-awaited forum for scientists from 15 coun-tries to discuss and concretize the "state-of-the-art" inthis discipline. The main themes treated are: Interface Phe-nomena, Convective Processes; Marangoni effects, Solidifica-tion, Combustion, Physico-Chemical Processes, MultiphasePhenomena, Residual Acceleration effects, Fluid Handling andNon-Newtonian Flows.
