Краткое описание

The present study is focused on the analysis of thermogravitational convection of an electrically conducting fluid in a rectangular annular space under the influence of an externally imposed time‐independent uniform magnetic field. The inner sides of the annulus are exposed to a higher temperature, whereas the outer sides are at lower temperature. Interest in such a study comes from its application in various scientific and industrial processes. Annular casings are made around many electrical devices. Heat generated by the devices is convected in the annular space, which occurs due to the thermogravitational effect and is affected by the imposed electromagnetic field. The solution is done by control volume integration. Modified MAC method is used for the numerical solution of governing equations. The gradient dependent consistent hybrid upwind scheme of second order (GDCHUSSO) is used for discretization of the convective terms. Comprehensive studies on controlling parameters that affect the flow and heat transfer characteristics are studied. Physics of the phenomenon is understood from the provided flowlines and isotherms. The results of the parametric study are provided in graphical and tabular form.
