Kurzbeschreibung des Verlags

This volume contains a large fraction of the papers presented at a symposium on Computational Approaches to Disperse Multiphase Flow, sponsored by the Inter- tional Union of Theoretical and Applied Mechanicsand generouslysupportedby the Of?ce of Basic Energy Sciences of the US Department of Energy. The symposium, which attracted about 90 participantsfrom?fteen differentcountries,was held at - gonne National Laboratory on October 4-7, 2004. There were 48 oral presentations and an additional 17 poster papers. Togetherwith experimentandtheory,computationhasbeenfora longtime an- tegralcomponentofmultiphase?owresearch. Astrikingfeaturecommontomost- pers presented at the symposium was the power, maturity and sophistication reached by this approach. Afewpapersconclusivelydemonstratethat,forsomeproblems,computingisthe only means by which key physical phenomena can be elucidated. A prime example is the analysis of Leonardo's paradox, i. e. , the instability of the rectilinear path of an ascending bubble. The explanation of the phenomenon rests on computations in which the bubble shape is constrained to remain spheroidal with a varying ecce- ricity - not a situation amenable to experiment, but a key step in understanding the physics. Another case in point is the study of the detailed action of surfactants at the surface of a rising bubble. While the general physical mechanism at work has been known for some time, this is the ?rst visualization of the microphysical processes acting at the bubble surface and their impact on the local ?ow ?eld. It is also interesting to realize that computation may be the key to interpreting experimental results.
