Magnetic field as it affects the three-dimensional structure of the self-oscillation regimes in free convection

Research output: Contribution to journalArticlepeer-review

Abstract

In the present study we offer results from investigations into the influence of a constant uniform magnetic field on the three-dimensional structure of the most dangerous infinitely small perturbation which leads to instability in steady convective flow; averaged and pulsating components of supercritical convective flows; the trajectories of fluid particles, governed by oscillatory convection regimes. Studying the action of a magnetic field on various spatial characteristics of oscillatory convective flows allows us to establish, in particular, both the qualitative and quantitative analogous changes in the spatial structure of the convective flows, which occur with an increase in the Hartman number or with a decrease in the Grashof number, as well as of the case for an increase in the Hartman number or an increase in the Prandtl number.
