“…Flows in porous space are of great interest due to their prevalence in nature. Such flows have a variety of scientific and engineering applications including studying underground water resources and seepage of water in river beds in agriculture engineering, filtration and purification processes in chemical engineering, and the movement of natural gases, oil, and water through reservoirs in petroleum technology [1,11,23,32]. Multiphase flow with heat transport is being studied in a number of fields.…”

“…A wide number of important practical problems of interest are unsteady. Further, despite a large number of oscillatory flow investigations in different flow configurations (see [6][7][8][9]11] and references therein), only a few investigations on immiscible flows with oscillatory pressure gradient have been documented. Umavathi et al [25] explored the heat transfer effect on the time-dependent flow of two immiscible liquids in a channel with transpiring walls that oscillate at a time-dependent normal velocity.…”

The MHD oscillatory flow of two immiscible, viscous liquids in a porous channel with heat transfer is the subject of this investigation. The two liquid layers with different viscosities flow in both regions. The analytical expressions for velocity and temperature distribution have been derived by solving the governing flow equations using the regular perturbation method. The effects of various parameters on the velocity, temperature, and Nusselt number have been shown graphically, and numerical values of skin friction and flow rate are presented in tabular form and discussed. According to our analysis, the mass flux reduces as the magnetic field strength rises. While the temperature of the liquid enhances with an increase in the Eckert number and the Prandtl number, the temperature distribution rises with a decrease in the thermal conductivity ratio. To validate the results, the analytical solutions are compared with the fourth-order numerical Runge–Kutta method coupled with the shooting approach, and the results are found to be in excellent agreement.

An analytical solution, based on the asymptotic series expansion method, for the problem of a fully developed chemically reactive laminar three-dimensional flow through a porous vertical infinite plate in a porous medium with sinusoidal permeability as suction in the existence of appreciable radiation is presented. The effects of the physical parameters entering into the problem on the flow and transport characteristics are studied and demonstrated through graphs. The flow is three-dimensional due to sinusoidal suction as well as porosity. It is found that concentration of the fluid rises due to thermal diffusion (Soret) effect. Furthermore, it is seen that fluid velocity is increased for increasing thermal diffusion effect. Also, viscous drag at the plate is increased under the Soret effect.

The problem of a hydromagnetic convective flow of an electrically incompressible viscous conducting fluid past a uniformly moving vertical porous plate is investigated analytically, taking into consideration radiation and thermal diffusion effects. A constant suction velocity is applied to the plate. A uniformly strong magnetic field is supposed to be applied normally to the plate and directed into the fluid region. To find a solution to the problem, an asymptotic series expansion method is used. The effects of thermal diffusion, magnetic field, porosity parameter, thermal radiation, and Grashof number are mainly focused on the discussion of the current problem. Increasing Soret number (Sr) hikes the velocity profile and skin friction but declines Sherwood number. Also, it has been found that, when the magnetic parameter (M) increased, the fluid velocity and the concentration profile decreased.The current results show a good deal of agreement with previously published work. The findings of this study could be relevant in a variety of applications, including diffusion processes involving molecular diffusion of species with molar concentration.
