Dynamics of a Gas Bubble near a Wall under Acoustic Excitation with the Formation of Cumulative Jet
Autor: L. A. Kosolapova
Publikováno v: Lobachevskii Journal of Mathematics. 42:2159-2164
The dynamics of a gas bubble near a rigid wall with the formation of a cumulative liquid jet under harmonic liquid pressure oscillation is studied. The initial shape of the bubble is varied from slightly oblate to slightly elongated spheroids of the

Publikováno v: Lobachevskii Journal of Mathematics. 42:24-29
A numerical study of the dynamics of a gas bubble in water near a plane rigid wall under ultrasound excitation has been performed. The bubble dynamics is excited at the natural frequency of the radial oscillations of the bubble in the absence of the

Influence of the Initial Shape of a Gas Bubble on Its Dynamics near a Wall under Acoustic Excitation
Autor: L. A. Kosolapova, V. G. Malakhov
Publikováno v: Lobachevskii Journal of Mathematics. 41:1235-1241
Influence of initial non-sphericity of a gas bubble on its dynamics at various distances from a plane rigid wall under harmonically varying liquid pressure is investigated. The initial shape of the bubble is taken to be a spheroid with the axis of sy

Dynamics of an Acoustically Excited Gas Cavity Attached to a Rigid Surface
Autor: L. A. Kosolapova, T. S. Guseva, V. G. Malakhov, A. A. Aganin
Publikováno v: Lobachevskii Journal of Mathematics. 40:1897-1903
Expansion, collapse and impact of a gas bubble onto a rigid wall are numerically studied. The bubble is adjacent to the wall, it is initially spherical, at the equilibrium state. Its dynamics results from harmonic variation of the surrounding liquid

Experimental Analysis and Empirical Model of the Complex Permittivity of Five Organic Soils at 1.4 GHz in the Temperature Range From −30 °C to 25 °C
Autor: Sergey Fomin, L. G. Kosolapova, Igor V. Savin, Valery Mironov
Publikováno v: IEEE Transactions on Geoscience and Remote Sensing. 57:3778-3787
The dielectric measurements were made for five organic soils taken from the tundra territories of Alaska, Yamal, and Taimyr, with the content of organic matter varying from 35% to 80%. The measurements were carried out in the temperature range from

Bubble dynamics near a locally curved region of a plane rigid wall
Autor: A. A. Aganin, L. A. Kosolapova, V. G. Malakhov
Publikováno v: Physics of Fluids. 34:097105
The dynamics of a bubble near a local axisymmetric convexity or concavity, cosine-like in the axial section, on a plane rigid wall is studied under conditions of formation of a cumulative liquid jet directed to the wall. The study is performed by the
