In this paper, the unsteady flow of two immiscible fluids with heat transfer is studied numerically with a modified cubic B-spine Differential Quadrature Method. Generalized Couette two immiscible dusty (fluid-particle suspension) and pure (Newtonian) are considered through rigid horizontal channels for three separate scenarios: first non-porous plates heat transfer, second porous uniform s...

Background: This paper explores the impact of thermal radiation on boundary layer flow of dusty hyperbolic tangent fluid over a stretching sheet in the presence of magnetic field. The flow is generated by the action of two equal and opposite. A uniform magnetic field is imposed along the y-axis and the sheet being stretched with the velocity along the x-axis. The number density is assumed to be...

Dusty galaxies with luminosities in excess of 10 L⊙ have been detected out to redshifts z ∼ 1 by the Infrared Space Observatory (ISO), and to higher redshifts using millimetre(mm)and submm-wave cameras on ground-based telescopes. The integrated properties of these more distant galaxies are also constrained by measurements of the intensity of the submm-wave background radiation. While it is gene...

Kelvin-Helmholtz (KH) instability plays a significant role in transport and mixing properties of any medium. In this paper, we numerically explore for two-dimensional strongly coupled dusty plasma with rotational shear flows. We study medium using generalized hydrodynamic fluid model which treats it as viscoelastic fluid. consider the specific cases rotating vorticity abrupt radial profiles rot...

A rotating dusty plasma apparatus was constructed to provide the possibility of experimental emulation of extremely high magnetic fields by means of the Coriolis force, observable in a corotating measurement frame. We present collective excitation spectra for different rotation rates with a magnetic induction equivalent of up to 3200 T. We identify the onset of magnetoplasmon-equivalent mode di...

The characteristics of arbitrary amplitude dust ion acoustic solitary waves (DIASWs) are studied in unmagnetized dusty plasmas whose constituents are cold uid ions, nonextensive electrons and stationary negative/positive dust particles. The pseudopotential approach has been used to investigate the structure of localized waves. It is found that, solitary waves exist in a definite interval for th...
