The Dynamic Behavior of Contracted and Jetting Process for an / 水下爆炸單一氣泡收縮及噴出破裂過程之動力行為

碩士 / 國立成功大學 / 造船工程學系 / 85 / The dynamic behavior of an explosive bubble is a complicated
phenomenon. The basic equations to simulate the behaviors are:
Laplace equation, Bernoulli equation and adiabatic state
equation. Three dimensional Boundary Element (BEM) is used to
solve boundary integral equation. The numerical algorithm is
found to be successful in simulating the collapse and jetting of
a single bubble in infinite domain. We discuss the numerical
convergence problem and compare with the 1-D Rayleigh-Plesset
equation in this paper. The research results are: contracted and
expanded diagrams of 1-D Rayleigh bubble; deformed history
diagrams of an underwater explosion bubble in the contracted
process; and the factors that result in bubble jetting are
gravity; pressure around the bubble and initial gas pressure of
an internal bubble. Bubble jetting can shorten the active time
of bubble collapse.
