论文摘要

在以前的一些论文之后,我们将继续在本文中证明声学世界与电磁世界之间的类比。因此,我们得出了:在内部簇中发现的气泡与从集群中发现的气泡之间的气泡之间的散射散射力(电声力),散射吸收力(引力 - 声力)在内部簇中发现的气泡,整个群集和整个气泡之间的气泡在群集中的气泡中的气泡之间的气泡之间的散射力(引力 - 声音),整个气泡的气泡,是一个外在的气泡,是一个外在的气泡,这些气泡的温度是浮标的温度。簇和声辐射的平均压力。我们的演算结果使我们发现气泡周围声辐射的平均压力的绝对值等于电声场的能量密度,等式。 (10)。这是本文最重要的结果。这些密度是对应于两个振荡气泡之间相互作用现象的气泡(气泡周围液体)的振荡的能量的密度。我们还证明,在群集内部的气泡之间的引力 - 声力是由于气泡中能量吸收而产生的,与气泡的虚拟质量的平方成正比。 (29)和(30)。

Following some previous papers, we continue in this paper to give proof of the analogy between the acoustic world and the electromagnetic world. Hence we derive the expressions for: the scattering-scattering force (the electro-acoustic force) between the bubbles found in the inner cluster and the bubble found out of the cluster, the scattering-absorption force (the gravito-acoustic forces) between the bubbles found in the inner cluster, the gravito-acoustic forces between the cluster as a whole and an outer bubble, the temperature corresponding to the translational motion of the bubbles in the inner cluster and the average pressure of the acoustic radiation. The results of our calculus led us to find out that the absolute value of the average pressure of the acoustic radiation around a bubble is equal to the density of the energy of the electro-acoustic field, Eq. (10). This is the most important result of this paper. These densities are the densities of the energy corresponding to the oscillation of the bubble (the liquid around the bubble) that are involved in the interaction phenomenon between two oscillating bubbles. We have also demonstrated that the gravito-acoustic forces, at resonance, between the bubbles inside the cluster, generated by the absorption of energy in the bubbles, are proportional to the square of the virtual masses of the bubbles, Eqs. (29) and (30).
