Oscillations for an equation arising in groundwater flow with the relaxation time
Mathematical Modelling and Analysis, 2011 Groundwater flow problems are mostly formulated by means of massbalance equation combined with Darcy's law. In this way, the flow is governed by a parabolic equation.

Passive swimming in viscous oscillatory flows
Physical Review E, 2016 Fluid-based locomotion at low Reynolds number is subject to the constraints of Purcell's scallop theorem: reciprocal shape kinematics identical under a time-reversal symmetry cannot cause locomotion. In particular, a single degree-of-freedom scallop undergoing opening and closing motions cannot swim. Most strategies for symmetry breaking and locomotion

Journal of Fluid Science and Technology, 2012 Turbulence in the oscillatory flow in realistic model human central airways was measured by particle image velocimetry (PIV) to reveal the nature of turbulence in a lung. The transparent silicone model of multi-branching airways was fabricated from X-ray

Dispersion in oscillatory flows
, 1983 The enhanced axial mixing which is caused by dispersion in oscillatory flows in some mass transfer devices may limit the reactor performance. This effect has provided the motivation for the present study in which oscillatory flow dispersion in a flat channel of large aspect ratio is investigated.

VARIATION OF SEDIMENT SUSPENSION IN OSCILLATORY FLOW
Coastal Engineering Proceedings, 1984 Different syphon type suspended load probes were used together with a newly developed 'carousel' sampler for measurements of the instantaneous sediment concentration in turbulent oscillatory flow over a sand bed. Shields parameters were well above the rippled/flat bed transition region, resulting in intense sediment transport over a flat bed.

Parametric instability in oscillatory shear flows [PDF]
Journal of Fluid Mechanics, 2003 In this article we investigate time-periodic shear flows in the context of the two-dimensional vorticity equation, which may be applied to describe certain large-scale atmospheric and oceanic flows. The linear stability analyses of both discrete and continuous profiles demonstrate that parametric instability can arise even in this simple model: the ...

The Effect of an Upstream Control Object in Low-Speed Rotation upon the Flow past a Long Plate
Journal of Fluid Science and Technology, 2011 In the present study, the authors consider a control of the flow past a semi-infinite plate with a blunt front. The flow is one of the simplest separated-and-reattaching flows, and can be a model such as heat exchangers and flow straighteners commonly ...
