The study of an immiscible fluid flow models is complex in nature and it has crucial applications in engineering and industry, such as powder technology, dust assortment, dust in gas cooling systems, retrieval of crude oil, waste water treatment, sedimentation process and nuclear reactors. Therefore, the current study deals with the steady flow of two immiscible dusty Newtonian and Casson fluids in a horizontal porous microchannel. The effect of magnetic field, electroosmotic forces, thermal radiation, viscous dissipation, Joule heating and chemical reactions have been considered into account. Initially, the flow model is considered with the well-known set of partial differential equations. Under the assumptions and non-dimensional quantities, the coupled governing differential equations have been transmuted to the non-dimensional ordinary differential equations. The exact solutions for the velocity, temperature and concentration of the fluid and dusty phases have been obtained in both the regions. The behaviour of non-dimensional emerging constraints on the flow, thermal and mass characteristics have been expressed through graphical representations. It is noticed that the dust particles volume fraction enhances the dusty Newtonian fluid as well as the dusty Casson fluid temperature. Escalating the values of Schmidt number declines the concentration profile of Newtonian and non-Newtonian dusty fluids.

The study of an immiscible fluid plays a significant role in the field of petroleum extraction, blood flow in arteries, hydrology, manufacturing process, and reservoir mechanics. These phenomena include immiscible fluids of different densities and viscosities in the same channel. Due to the various practical applications, in the current study, the generalized Couette flow of two immiscible fluids (Newtonian and non‐Newtonian fluids) of different viscosities between two infinite parallel plates under the presence of constant pressure gradient and electroosmosis is addressed. The effects such as electromagnetohydrodynamics, zeta potential, Joule heating, thermal radiation, modified Darcy's law, and chemical reaction have been also considered into account. The dimensional system of equations has been nondenationalized with suitable dimensionless quantities. The resulting nondimensional system of coupled flow equations has been solved analytically. The solutions for the velocity, temperature, and concentration have been presented. The effect of various pertinent fluid flow parameters has been displayed graphically. The current study concludes that both the velocity and temperature profiles decrease with the increase in Hartmann number and radiation parameter, whereas an increase in chemical reaction parameter uplifts the concentration of both fluids.

The study of electromagnetohydrodynamics (EMHD) of non‐Newtonian fluid plays a significant role for optical design, thermal management of electronic components, and various operations of microfluidic devices. The use of parallel geometry is seen in the circulatory system, extrusion process, and respiratory system. By considering various practical applications, in the current study, the Poiseuille flow of an incompressible Casson liquid between the plates is investigated. The effects of MHD, Joule heating, thermal radiation, modified Darcy's law, and chemical reaction have been taken into account. The dimensional governing equations have been converted into dimensionless equations with pertinent nondimensional quantities. The resulting system of nondimensional system of equations has been analytically solved with nondimensional slip boundary conditions. The graphical results have been displayed with various fluid flow parameters. From the current study, it is concluded that the influence of Darcy number and Casson fluid parameter enhances the velocity profile, but the concentration declines with the enhancement of Casson fluid parameter. The radiation parameter and Prandtl number suppress the temperature profile.
