Natural convection of magnetic fluid in a rectangular Hele-Shaw cell

Magnetic fluid rheology and flows

“…(1) [131]. Other ferrofluid Hele -Shaw cell flows investigated azimuthal magnetic fields from a long straight current-carrying wire along the axis perpendicular to the walls with a timedependent gap [132,133]; labyrinthine instability in miscible magnetic fluids in a horizontal Hele -Shaw cell with a vertical magnetic field [134]; theory and experiments of interacting ferrofluid drops [135 & ]; numerical simulations [136] and measurements [137] of viscous fingering labyrinth instabilities; fingering instability of an expanding air bubble in a horizontal Hele -Shaw cell [138] and of a rising bubble in a vertical Hele-Shaw cell [139]; fingering instabilities of a miscible magnetic fluid droplet in a rotating Hele -Shaw cell [140]; theory and experiments of the Rayleigh -Taylor instability [141 & ]; and natural convection of magnetic fluid in a bottom-heated square Hele-Shaw cell with two insulated side walls with heat transfer measurements and liquid crystal thermography [142].…”

Correlation for Nusselt number in pure magnetic convection ferrofluid flow in a square cavity by a numerical investigation

“…In recent years, a number of experiments and numerical calculations have been presented to describe the phenomenon of magnetic convection [1][2][3][4][5][6][7][8][9]. Tangthieng et al [2] presented simulations of heat transfer to a ferrofluid in the presence of a magnetic field (a permanent magnet placed on top) for the cases of flow between flat plates and in a square box.…”

“…Ganguly et al [7] simulated forced convection heat transfer during the flow of a ferrofluid in a channel under the influence of a two-dimensional magnetic field created by a line-source dipole. Wen and Su [8] experimentally studied the natural convection of a magnetic fluid in a square Hele-Shaw cell using heat transfer measurements and liquid crystal thermography. Jue [9] analyzed ferrofluid flow driven by thermal buoyancy and magnetic force in a cavity in order to study the interaction between these two factors in a confined domain.…”

Numerical study of non-uniform magnetic fields effects on subcooled nanofluid flow boiling

“…In the literature, there are many investigations which were carried out in the field of thermomagnetic convection of the ferrofluids for different geometries in the presence of an external magnetic field (Kikura et al, 1993;Yamaguchi et al, 1999;Wen et al, 2002;Krakov and Nikiforov, 2002;Yamaguchi et al, 2002;Snyder et al, 2003;Wen and Su, 2005;Jafari et al, 2008;Aminfar et al, 2011Aminfar et al, , 2012Aminfar et al, , 2013. They presented that the heat transfer capabilities of the magnetic fluids were changed by both the intensity of external magnetic field and temperature gradient.…”
