Thermo-magnetic convection in ferrofluids with gravity-modulation

نویسنده

  • Renu Bajaj
چکیده

Convection in magnetic tluids is considered in the presence of vertical magnetic field and periodicall y modul ated gravitational fie ld. Depending upon the different physical parameters, modulation may have destabilizing effect on the unmodulated stable system. Also, the unstable system may get stabilized with modulation. Instability may occur either as subharmonic instability or harmonic instability. Using Floquet theory, the regions of parameu'ic instability have been obtained.

Magnetic action on convection and heat transfer in ferrofluid

The interplay of buoyancy and thermo-magnetic convection mechanisms are investigated in a horizontal ferrofluid layer heated from one wide side and cooled from another in the presence of external uniform transversal magnetic field. The influence of gravitational settling of magnetic particles and their aggregates on heat transfer and convection instability is also considered. The ferro-colloids...

Magneto-Thermo-Elastic Stresses and Perturbation of Magnetic Field Vector in a Thin Functionally Graded Rotating Disk

In this paper, a semi-analytical solution for magneto-thermo-elastic problem in an axisymmetric functionally graded (FG) hollow rotating disk with constant thickness placed in uniform magnetic and thermal fields with heat convection from disk’s surfaces is presented. Solution for stresses and perturbation of magnetic field vector in a thin FG rotating disk is determined using infinitesimal theo...

Thermoconvection in magnetized ferrofluids: The influence of boundaries with finite heat conductivity

Realistic boundaries of finite heat conductivity for thermoconvection in a Rayleigh-Bénard setup with magnetized ferrofluids are investigated. A linear stability analysis of the conductive state is performed with a shooting method. It shows that the critical wave number is for any magnetic field stronly influenced by the conductivity of the boundaries. Linear as well as nonlinear coefficients o...

Global stability results for temperature modulated convection in ferrofluids

The evolution of the energy functional in a dynamical system which arises from the stability of the time periodic temperature modulated state of the Rayleigh–Bénard convection in a horizontal thin fluid layer; results in a deviation of the critical nonlinear stability boundary from the linear instability boundary. If the fluid under consideration is magnetically polarizable, the deviation is fu...

Investigation of handmade ferrofluids' motion in a ventilated cavity using computational fluid dynamics

In this research, some more applicable ferrofluids are produced and their mechanical specifications are measured, experimentally. Also, their treatments in the ventilated cavity geometry are assessed numerically. The magnetite nanoparticles are produced by a chemical combination of Fe2+ and Fe3+ with NH3. In order to solve the nanoparticles in the new mediums, a...
