Article
Infrared camera visualisation of convective flows in differentially heated vertical layers with the height-to-thickness ratios of 30 and 62.5 was used to demonstrate the influence of concentration stratification caused by gravitational sedimentation of magnetic particles and aggregates on the structure of convective motion. It is found that when a...
Article
Flow patterns arising in a vertical differentially heated layer of nonconducting ferromagnetic fluid placed in an external uniform transverse magnetic field are studied experimentally and discussed from the point of view of the perturbation energy balance. A quantitative criterion for detecting the parametric point where the dominant role in genera...

... In general, it is necessary to take into account gravitational sedimentation, since the concentration redistribution strongly affects convective instability and nonlinear flows of colloidal suspensions. Convective flows of the magnetic fluids have been experimentally investigated in the cavities of different geometries: linked channels [18,19], spherical cavity [20], vertical or horizontal layer [21,22]. ...
... In this work, we have explored to what extent a multi-effect conversion system can be exploited by combining together the effects of thermomagnetic advection, triboelectricity and pyroelectricity, using a mixed colloid and focusing on synergistic effects that could arise and make such technology particularly profitable.

... Because the magnetic susceptibility for a FF is usually several orders of magnitude larger than ordinary para-or dia-magnetic fluids, the magnetic field required for many intriguing phenomena is much smaller. Several groups have observed the magnetically induced convection in FF [11][12][13][14][15] in a relatively low fields. Most of the experiments were done in a uniform magnetic field [16][17][18]. ...
