“…In recent days dusty fluid has a wide range of applications like atmospheric fields, wastewater treatment, Metal objects covered with plastic materials and solids drying, recovery of crude oil from pores of reservoir rocks and purification, soil salvation by natural winds, power plant piping, conveying of powdered materials, Coal gasification for power generation, Production of granular polyethylene, food pharmaceutical industries particularly for efficient cultivation of microorganisms, lunar surface erosion by the exhaust of a landing vehicle, fluidized beds and fluid droplet sprays. 1,2 Souayeh et al 3 presented a steady two-dimensional boundary layer flow and heat transfer rate over the stretching surface of an incompressible dusty hybrid nanofluid. Hady et al 4 studied the numerically 2D laminar natural convection flow of a micropolar dusty fluid with convective boundary conditions over a stretching surface.…”

The main intention of this article is to explore the significance of electronmagnetohydrodynamic (EMHD) dusty nanofluid on the stagnation point flow in the presence of radiation and Ohmic heating. Water is considered as base fluid with single-wall carbon nanotubes along with suspended dust particles. The numerical solutions for both dusty phase and fluid phase differential systems are obtained by using Runge Kutta 4th order with shooting method. Influence of embedded parameters such as Biot number, electric field, viscous dissipation, magnetic field, thermal radiation, Joule heating and stagnation point flow are presented graphically. Dust particles play a significant role in food pharmaceutical industries particularly for efficient cultivation of microorganisms and also these type of studies may be applicable in atmospheric fields, wastewater treatment, metal objects covered with plastic materials and solids drying. The higher values of electric field parameter ( E) increases the fluid phase velocity and dusty phase velocity. An increase in the thermal radiation parameter releases thermal energy into the flow, so this energy helps to increase the fluid phase temperature and dusty phase temperature. The fluid phase temperature and dusty phase temperature declines with increasing the electric field parameter for dusty fluid and dusty nanofluid cases.

“…Wahid [28] used the Marangoni flow model to study the influence of suction on mass and heat transport in the nanofluid boundary layer. Hossain [29] analyzed the influence of natural convection on a laminar unsteady fluid moving along a vertical perforated plate in a porous medium. Considering the natural convective flow over an infinite vertical flat plate, Sandeep [30] developed a mathematical model to analyze the influence of thermal radiations on the heat and mass transfer of nanofluids.…”

The flow of nanofluids is very important in industrial refrigeration systems. The operation of nuclear reactors and the cooling of the entire installation to improve safety and economics are entirely dependent on the application of nanofluids in water. Therefore, a model of Maxwell’s dusty nanofluid with temperature-dependent viscosity, surface suction and variable surface tension under the action of solar radiation is established. The basic equations of momentum and temperature of the dust and liquid phases are solved numerically using the MATLAB bvp4c scheme. In the current evaluation, taking into account variable surface tension and varying viscosity, the effect of dust particles is studied by immersing dust particles in a nanofluid. Qualitative and quantitative discussions are provided to focus on the effect of physical parameters on mass and heat transfer. The propagation results show that this mixing effect can significantly increase the thermal conductivity of nanofluids. With small changes in the surface tension parameters, a stronger drop in the temperature distribution is observed. The suction can significantly reduce the temperature distribution of the liquid and dust phases. The stretchability of the sheet is more conducive to temperature rise. The tables are used to explain how physical parameters affect the Nusselt number and mass transfer. The increased interaction of the liquid with nanoparticles or dust particles is intended to improve the Nusselt number. This model contains features that have not been previously studied, which stimulates demand for this model among all walks of life now and in the future.

“…They created the flow by an exponentially stretching of a flat sheet with solar radiation. Natural convection of dusty nanofluid was proposed by Siddiqa et al 34 Hossain et al 35 studied the role of a small discrepancy in surface temperature and free stream velocity in mixed convection flow of dusty fluid. Very recently, Mustafa 36 reported the analytical solution for the two-phase dusty fluid flow over deforming isothermal surfaces.…”

This article addresses the time-dependent two-phase magnetohydrodynamic squeezing flow of dusty liquid. The fluid flow is considered in a rotating channel. The flow is constructed by squeezing of an upper plate and stretching of the lower plate and relevant equations are obtained. Numerical results are computed by utilizing shooting method along with the RK–Fehlberg scheme. The obtained solutions are validated by comparison with the existing analytical solutions. The effects of pertinent parameters on velocities of both phases are comprehensively discussed through graphical results. The numerical values of shear stress of both phases at lower and upper walls are also tabulated. Furthermore, the slope of the linear regression line through data points is determined in order to quantify the increase/decrease. Numerical simulations disclosed that the normal and transverse velocities are decreased due to stronger Coriolis force. It is also established that the velocities of the fluid phase are higher than that of the dust phase
