“…They also observed that dusty particle density attains a peak at the plate (sheet) surface. Dalal et al 21 presented central and second upwind finite difference computational solutions for natural convection of a dusty fluid in an infinite rectangular channel with differentially heated vertical walls and adiabatic horizontal walls. They noted that the heat transfer rate at the channel walls (Nusselt number) is reduced with an increase of mass concentration of dust particles, whereas it is boosted with a higher thermal buoyancy effect (Rayleigh number).…”

In this paper, the unsteady flow of two immiscible fluids with heat transfer is studied numerically with a modified cubic B-spine Differential Quadrature Method. Generalized Couette flow of two immiscible dusty (fluid-particle suspension) and pure (Newtonian) fluids are considered through rigid horizontal channels for three separate scenarios: first for nonporous plates with heat transfer, second for porous plates with uniform suction and injection and heat transfer, and third for nonporous plates with interface evolution. The stable

“…Now the dusty fluid definition is a blend of particles in micrometer-sized and the base fluids and characterized by tremendous applications in various fields. [6][7][8][9] In 1998, Dalal et al 10 presented the heat transfer and dusty fluid flow inside an infinite closed rectangular channel with the adiabatic horizontal walls and heated vertical walls. It is observed increasing the heat transfer rate due to an enhancement in Rayleigh number values, while it reduces with increasing of mass concentration of the dust particles.…”

Heat transfer due to a square Darcy porous cavity in the presence of dust particles and thermal radiation effect by applying the thermal non-equilibrium model is investigated numerically in the current paper. The square cavity is maintained at a hot temperature at the left side wall, and the right side wall is maintained at cold temperature. While the bottom and top walls of the cavity are considered adiabatic. The impact of governing physical parameters on the streamlines, isotherms contours for the fluid and dust phases and isotherms for the solid phase are tested and represented through Graphic. In addition, the profiles of the average Nusselt numbers for solid and fluid phases and the total average Nusselt number are presented. The finite difference method is convenient to obtain a numerical analysis of the non-dimensionalized equations via the influence of mass concentration of the dust particles, fluid-particle interaction parameter for velocity, fluid-particle interaction parameter for temperature, Eckert number, radiation parameter, Rayleigh number, modified conductivity ratio, and inter-phase heat transfer coefficient. The results urge that the presence of dust particles leads to reduces the heat transfer rate at the left wall of the enclosure.

“…Vajravelu and Nayfeh [21] have explored MHD dusty fluid flow past a stretching sheet. The dynamics of two-phase flow was scrutinized by a number of authors with some various physical conditions (Sivaraj and Kumar [22]; Singh and Singh [23]; Dalal [24]). Flows of mixed convection are of massive interest due to their variety scientific, engineering, and industrial applications in heat and mass transfer.…”

A theoretical analysis for magnetohydrodynamic (MHD) mixed convection of non-Newtonian tangent hyperbolic nanofluid flow with suspension dust particles along a vertical stretching sheet is carried out. The current model comprises of non-linear partial differential equations expressing conservation of total mass, momentum, and thermal energy for two-phase tangent hyperbolic nanofluid phase and dust particle phase. Primitive similarity formulation is given to mutate the dimensional boundary layer flow field equations into a proper nonlinear ordinary differential system then Runge-Kutta-Fehlberg method (RKF45 method) is applied. Distinct pertinent parameter impact on the fluid or particle velocity, temperature, concentration, and skin friction coefficient is illustrated. Analysis of the obtained computations shows that the flow field is affected appreciably by the existence of suspension dust particles. It is concluded that an increment in the mass concentration of dust particles leads to depreciate the velocity distributions of the nanofluid and dust phases. The numerical computations has been validated with earlier published contributions for a special cases.
