The Brinkman model is used to study the criterion of appearance of station- ary convection in a porous horizontal layer saturated by a binary mixture of ferrofluids and heated from below. The analytical expression of the Rayleigh number is determi [...]
In this paper we studied the onset of instability in a horizontal layer of a rotating ferrofluid in the presence of the helical force. The analytical expression of the Rayleigh number of the system is determined as a function of the dimensionless n [...]
Stability characteristics of the flow of incompressible viscous fluid, subjected to a uniform magnetic field are investi- gated. The temporal evolution of infinitesimal perturbations is performed by spectral computation of Navier-Stokes equations. [...]

This work studies the nonlinear dynamics and passive control of chemical oscillations governed by a forced modified Van der Pol–Duffing oscillator. We considered the dynamics of nonlinear chemical systems subjected to fluctuating hydrodynamic drag fo [...]
This paper addresses the issue of a mixed Rayleigh–Liénard oscillator with external and parametric periodic-excitations. The Melnikov method is utilized to analytically determine the domain boundaries where horseshoe chaos appears. Routes to chaos ar [...]
