چکیده

The response of a magnetic field perpendicular to the interface on Rayleigh-Taylor instability (RTI) is investigated when mass along with heat transferring through interface. fluids considered in this analysis are electrically as well thermally conducting, viscous, and incompressible. top-heavy system such way that liquid lies above its vapor. governing nonlinear partial differential equations linearized perturbed state. well-known normal mode procedure utilized critical value wavenumber calculated determine stability/instability This found be function fluid viscosities, transfer coefficient, densities, etc. Various plots showing effect heat/mass transfer, field, have been made illustrated physically. We achieve transport at reduces amplitudes perturbations.

Rayleigh-taylor instability with magnetic fluids: experiment and theory

We present experiments showing the Rayleigh-Taylor instability at the interface between a dense magnetic liquid and an immiscible less dense liquid. The liquids are confined in a Hele-Shaw cell and a magnetic field is applied perpendicular to the cell. We measure the wavelength and the growth rate at the onset of the instability as a function of the external magnetic field. The wavelength decre...

Study on Electrohydrodynamic Rayleigh-Taylor Instability with Heat and Mass Transfer

The linear analysis of Rayleigh-Taylor instability of the interface between two viscous and dielectric fluids in the presence of a tangential electric field has been carried out when there is heat and mass transfer across the interface. In our earlier work, the viscous potential flow analysis of Rayleigh-Taylor instability in presence of tangential electric field was studied. Here, we use anoth...

Granular Rayleigh-Taylor instability

A granular instability driven by gravity is studied experimentally and numerically. The instability arises as grains fall in a closed Hele-Shaw cell where a layer of dense granular material is positioned above a layer of air. The initially flat front defined by the grains subsequently develops into a pattern of falling granular fingers separated by rising bubbles of air. A transient coarsening ...

Rayleigh-Taylor instability with complex acceleration history.

Experiments and numerical simulations are performed on the Rayleigh-Taylor instability with a complex acceleration history g(t) consisting of consecutive periods of acceleration, deceleration, and acceleration. The dominant bubbles and spikes that grow in the initial unstable phase are found to be shredded by the trailing structures during the stable deceleration phase. This reduces their diame...

Effects of Magnetic Field, Sheared Flow and Ablative Velocity on the Rayleigh - Taylor Instability

It is found that magnetic field has a stabilization effect whereas the sheared flow has a destabilization effect on the RT instability in the presence of sharp interface. RT instability only occurs in the long wave region and can be completely suppressed if the stabilizing effect of magnetic field dominates. The RT instability increases with wave number and flow shear, and acts much like a Kelv...
