Interaction of two cavitation bubbles with a rigid boundary

J. R. Blake、P. B. Robinson、A. Shima 等 4 位作者1993-10-01Journal of Fluid Mechanics

The motion of two cavitation bubbles near a rigid boundary is observed experimentally using a high-speed camera and compared against numerical solutions obtained using a boundary integral method. The comparisons are favourable with regard to both bubble shape history and centroid motion. The bubbles show a range of re…

Synthesis and properties of poly(hydroxyurethane)s

Nobuhiro Kihara、Takeshi Endo1993-10-01Journal of Polymer Science Part A Polymer Chemistry

Abstract Bis(cyclic Carbonate)s 1 were prepared by the reaction of bis(epoxide)s and atmospheric pressure of CO 2 in the presence of sodium iodide and triphenylphosphine as catalysts at 100°C in high yield. Polyaddition of 1 and hexamethylenediamine ( 2a ) or dodecamethylenediamine ( 2b ) in dimethylsulfoxide or N , N…

Pressure-induced phase transition in SiC

Minoru Yoshida、Akifumi Onodera、Masaki Ueno 等 5 位作者1993-10-01Physical review. B, Condensed matter

X-ray diffraction studies have been made of cubic (3C) and hexagonal (6H) polytypes of SiC under pressures to 105 and 95 GPa, respectively, using a diamond-anvil cell and an imaging plate technique. 3C-SiC undergoes a phase transition into the rocksalt-type structure at 100 GPa or higher accompanied by a volume reduct…
