Effect of hydrodynamics on mass transfer in a gas-liquid oscillatory baffled column [PDF]
, 2004 In this paper, we present an experimental study on mass transfer of oxygen into water in an oscillatory baffled column (OBC). The objective of this work is to establish the contribution of individual parameters, such as the size of bubbles and the gas ...

Oscillatory Motion of a Camphor Object on a Surfactant Solution
The Journal of Physical Chemistry B, 2021 The mode bifurcation between oscillatory motion and no motion of a camphor object floating on surfactant aqueous solution was investigated. The camphor and surfactant were used as the sources of driving and suppressing forces, respectively. A circular plastic sheet was attached to the center of the bottom of a camphor disk, which served as the self ...

Scale-up of oscillatory flow mixing [PDF]
, 2011 Oscillatory Flow Mixing is a recent development in mixing technology which has evolved over the past decade. It has a number of similarities to other mixing technologies, particularly pulsed and reciprocating plate columns, but at the laboratory scale ...

The Existence of Oscillatory Solutions for a Nonlinear Differential Equation [PDF]
SIAM Journal on Mathematical Analysis, 1972 For the differential equation $\ddot y + q(t)y^\gamma = 0$, where $q(t)$ is nonnegative and continuous and $0 < \gamma \ne 1$, a necessary and sufficient condition for the oscillation of all solutions is known. However, it is possible for oscillatory and nonoscillatory solutions to coexist. This paper gives sufficient conditions for the existence of

On oscillatory solutions of differential inequalities [PDF]
Czechoslovak Mathematical Journal, 1992 Oscillation properties are proved for systems of differential inequalities of the type \(\alpha_ iy_ i'y_{i+1}>0\) for \(y_{i+1}\neq 0\), \(y_ i'=0\) if \(y_{i+1}=0\), \(i=1,\dots,n\) in an interval \((a,b ...

Asymptotic behavior of oscillatory solutions
Hiroshima Mathematical Journal, 1988 The aim in this paper is to study the asymptotic behavior of the oscillatory solutions of certain delay differential equations of the form \[ (1)\quad x'(t)+p(t)x(t-\tau)+q(t)x(t-\sigma)=0,\quad t\geq t_ 0 \] and of certain neutral equations of the form \[ (2)\quad (d/dt)[x(t)- px(t-\tau)]+q(t)x(t-\sigma)=0,\quad t\geq t_ 0.

On numerical methods for highly oscillatory problems in circuit simulation [PDF]
, 2009 We propose in this paper a novel technique for an efficient numerical approximation of systems of highly oscillatory ordinary differential equations. In particular, we consider electronic systems subject to modulated signals.
