固体基底上可压缩半球形气泡的线性振动

Linear oscillations of a compressible hemispherical bubble on a solid substrate

Sergey Shklyaev, Arthur V. Straube

摘要:

本文对固体基底上半球形气泡的线性自然振动和强迫振动进行了理论研究。考虑接触线动力学与霍金条件,这最终导致的形状和体积振荡的相互作用。共振现象,主要是与固定的接触线或与固定的接触角的气泡,被发现。研究了弱可压缩气泡的极限情况。得到了气泡可压缩性是否可以忽略的一般判据。

英文摘要:

The linear natural and forced oscillations of a hemispherical bubble on a solid substrate are under theoretical consideration. The contact line dynamics is taken into account with the Hocking condition, which eventually leads to interaction of the shape and volume oscillations. Resonant phenomena, mostly pronounced for the bubble with the fixed contact line or with the fixed contact angle, are found out. The limiting case of weakly compressible bubble is studied. The general criterion identifying whether the compressibility of a bubble can be neglected is obtained.
