Journal of Applied Physics , Cited by: If we inject air into a Hele-Shaw cell that is otherwise filled with viscous fluid, we can observe a bubble of air growing in size. The process is highly unstable, and the bubble boundary expands in an uneven fashion, leading to striking fingering patterns (look up Hele-Shaw cell .

In neutral fluids and plasmas, the analysis of perturbations often starts with an inventory of linearly unstable modes.

Then, the nonlinear steady-state is analyzed or predicted based on these linear modes. A crude analogy would be to base the study of a chair on how it responds to infinitesimaly small perturbations. One would conclude that the chair is stable at all frequencies, and cannot Author: Maxime Lesur, Julien Médina, Makoto Sasaki, Akihiro Shimizu.

At leading order, the pressure driven flow in the cell has a Poiseuille profile, and the situation can be described by a depth-averaged two-dimensional potential flow model, where the mean in-plane velocity is proportional to the pressure gradient in each fluid, with the proportionality constant scaling inversely with the viscosity and with the Cited by: This book highlights some recent advances in interfacial research in the fields of fluid mechanics and materials science at the beginning of the twenty-first century.

It is an extension of the presentations made during the conference “Interfaces for the 21st Century,” held on. The theory of the Rayleigh-Taylor instability of accelerated fluid layers is systematically developed from basic fluid equations.

His seminal paper, “Asymptotic theory of spherical electrostatic probes in a slightly ionized, collision dominated gas” (; Physics of Fluids, 6, e), is to date the most highly.

Control over Saffman-Taylor instability which otherwise randomly rearranges viscous fluid in a ’lifted Hele- Shaw cell’ is exercised for the same. The proposed fluid shaping control employs anisotropies on cell plates, to shape a stretched fluid film into a network of ordered multiscale tree-like patterns and well defined webs/meshes.

Specific studies of convection in a Hele-Shaw cell were reported by Cooper et al. (), Goldstein et al. (), and Gorin et al. The Hele-Shaw cell experiments are especially useful for revealing streamline patterns when the walls are made of transparent material.

This study of translating air bubbles in a Hele-Shaw cell containing viscous fluid reveals the critical role played by surface tension in these systems.

The standard zero-surface-tension model of Hele-Shaw flow predicts that a continuum of bubble solutions exists for arbitrary flow translation velocity.
