Calculation of the Collapse Process for a Spherical Gas (Vapor) Bubble in a Pipe

摘要

The collapse process is considered for a spherical gas (vapor) bubble formed at the center of symmetry of a horizontal pipe filled with ideal fluid. An analytical expression is obtained for the time dependence of the bubble radius. The solution is generalized to the nonsymmetric case of a bubble collapsing at an arbitrary point inside the pipe.
