要約

An analytical study of the two-fluid hydromagnetic unsteady mixed convective flow of viscous, incompressible, electrically conducting, immiscible liquids in a horizontal channel is investigated. Both liquids are considered to have different densities, viscosities, and thermal and electrical conductivities, and occupy equal heights. The transport properties of both liquids are taken to be constant and the bounding channel walls are maintained at constant and equal temperature. A regular perturbation technique is applied to obtain the solutions of velocity field and temperature distribution of both liquids. Expressions for skin frictions and heat transfer rates at the plates are also derived. The effects of various parameters entered into the equations of momentum and energy are evaluated numerically and plotted graphically, while numerical values of variations in skin frictions and heat transfer rates at the plates are presented in tabular form. The results of the study are discussed.
