Motion of Bubbles and Drops in Reduced Gravity

Abstract

Items with a reviewer byline (coded R) are by AMR's corps of dedicated outside volunteer reviewers. AMR will attempt to get critical reviews of all relevant textbooks, reference works, and monographs. Items without a reviewer byline (coded N) are prepared by AMR in-house staff and are largely based on material such as a book's table of contents and editor's preface or foreword. In the interest of timeliness, most conference proceedings and multi-author contributed volumes will receive descriptive notes in this fashion. Books deemed to be somewhat peripheral to AMR's basic scope may simply be listed

Bubble Dynamics in Nucleate Pool Boiling on Thin Wires in Microgravity

“…In general, the value of K must be determined by experiments. In the plane case, K tends to about 0.3 when the Marangoni number tends to infinity (Subramanian and Balasubramaniam 2001). Further decrease may be observed in the present case due to the difference from the plane case.…”

Thermocapillary Migration of Deformable Bubbles at Moderate to Large Marangoni Number in Microgravity

“…Thus, it attracts much more interests of researchers all over the world along with the progress of human space activities. However, most of the work on this subject is relatively recent, as summarized in the monograph by Subramanian and Balasubramaniam (2001). Focusing upon the present topic, only studies relating to the thermocapillary migration of gas bubble are briefly reviewed here.…”

Heterogeneous nucleation in hypermonotectic aluminum alloys

“…Nucleation is stimulated by the available TiB 2 . In later stages those lead droplets are covered by Al 3 Ti and therefore cannot act as nucleation centers for lead anymore and such a coverage reduces drastically an Marangoni motion of droplets and coagulation thereby [8]. So the overall droplet density is less compared to samples containing TiB 2 .…”
