Nonaxisymmetric disturbances in compound liquid jets falling under gravity
Physical Review E, 2016The disintegration of a compound thread of fluid can be utilized in a wide variety of applications including the production of compound droplets or capsules. In this paper we investigate the linear instability of a compound inviscid liquid jet falling under gravity in a surrounding gas with respect to nonaxisymmetric waves.

The differences between gravity anomalies and gravity disturbances are numerically investigated in this study. In particular, we demonstrate how the topography, atmosphere and mass irregularities enclosed within the geoid contribute to these differences. The numerical analysis is conducted at the area of study in the Canadian Rocky Mountains.

Comparison of undulation difference accuracies using gravity anomalies and gravity disturbances
Bulletin Géodésique, 1980Errors in the outer zone contribution to oceanic undulation differences computed from a finite set of potential coefficients based on satellite measurements of gravity anomalies and gravity disturbances are analyzed. Equations are derived for the truncation errors resulting from the lack of high-degree coefficients and the commission errors arising ...

On a rotational flow disturbed by gravity
Journal of Fluid Mechanics, 1976We examine a rapidly rotating flow that exhibits periodic vortex detachment. Specifically, the rotation/symmetry axis of a fluid-filled cylinder is set perpendicular to gravity. A free buoyant cylindrical float placed within the container is acted upon by both centrifugal and gravitational forces, the competition of which causes fluid motion and, in ...

On gravity‐capillary waves due to interface disturbance
International Journal of Mathematical Education in Science and Technology, 1997The generation of gravity‐capillary waves at the interface between two superposed fluids due to interface disturbance is considered, assuming linear theory. Fourier and Laplace transform techniques are employed in the mathematical analysis and the form of the interface depression is obtained as an infinite integral involving oscillatory functions when ...

Capillary gravity waves caused by a moving disturbance: Wave resistance
Physical Review E, 1996The dispersive property of capillary gravity waves is responsible for the complicated wave pattern generated at the free surface of a calm liquid by a disturbance moving with a velocity V greater than the minimum phase speed ${\mathit{c}}^{\mathrm{min}}$=(4g\ensuremath{\gamma}/\ensuremath{\rho}${)}^{1/4}$ (\ensuremath{\rho} is the liquid density ...

A new mathematical model for evaluation of the third-order (disturbing) gravitational tensor is formulated in this article. Firstly, we construct corresponding differential operators for the components of the third-order (disturbing) gravitational tensor in a spherical local north-oriented frame.

Integral formulas are derived for the determination of geopotential coefficients from gravity anomalies and gravity disturbances over the surface of the Earth. First order topographic corrections to spherical formulas are presented. In addition new integral formulas are derived for the determination of the external gravity field from surface gravity.

The theory of atmospheric disturbances induced by gravity field inhomogeneities
Doklady Earth Sciences, 2014Linear disturbances induced by gravity-field inhomogeneities in a horizontal stratified flow with a vertical shear are calculated analytically. In addition to being dependent on the amplitude of these inhomogeneities, disturbances depend strongly on their horizontal scales, background flow velocity, stratification, and Coriolis parameter.
