摘要：

The problem of the behavior of a bubble attached to a solid wall was solved numerically by the variational method, in which the viscosity and compressibility in the liquid are neglected. The effects of the surface tension and the contact angle on the collapsing bubble were taken into account. As a result, it was clarified that for the contact angle α < 90 ° the projecting part of liquid advancing against a solid wall was formed in the collapsing process regardless of the amount of gas in the bubble and the bubble size, and that the effects of the Weber number and the contact angle on the bubble shape were large, while the effect of amount of gas in the bubble was small. © 1979 Springer-Verlag.
