“…Thermoconvective stability of ferrofluids without considering buoyancy effects has been investigated by Lalas and Carmi [15], whereas Shliomis [16] analyzed the linearized relation for magnetized perturbed quantities at the limit of instability. Kumar and Chandra [17] considered the flow of a magnetic fluid through a channel in the presence of a transversely applied magnetic field and studied the flow behavior for various parameters. The stability of a static magnetic fluid under the action of an external pressure drop has been studied by Polevikov [18], whereas the thermal convection in a magnetic fluid has been considered by Zebib [19].…”
