“…It was pointed out by Fortov et al [29] that there exists equality between the force exerted on the gas by the dust and force exerted on the dust by the gas. Bilal et al [30] studied the viscoelastic fluid subject to dust particles; Jalil et al [31] examined the exact solution of the boundary value fluid problem; Reena and Rana [32] considered the micropolar fluid subject to solid dust particles; Dasman et al [33] analyzed the non-Newtonian fluid incorporation of dust particles. More work on dusty fluid subject to various types of geometries was carried out in [34][35][36][37][38].…”

The main objective of this investigation to examine the momentum and thermal transportation of rotating dusty micropolar fluid flux with suspension of conducting dust particles across the stretched sheet. The novelty of the flow model is the exploration of the significance of boosting the volume concentration of dust particles in fluid dynamics. The governing PDEs of the problem for both phase models are transmuted into nonlinear coupled non-dimensional ODEs by utilizing suitable similarity modifications. The bvp4c technique was utilized in MATLAB script to acquire a graphical representation of the experimental results. This study illustrates the analysis of repercussions of pertinent parameters on non-Newtonian fluid and the dusty phase of fluid. By improving the volume concentration of dust particles and rotating parameters, the axial velocity for both phases depreciates, whereas temperature and transverse velocity for both phases have the opposite behavior. The micro-rotation distribution rises with higher contributions of rotating and material parameters, whereas it decreases against larger inputs of volume concentration of dust particles. The growing strength of the dust volume fraction (ϕd) caused the coefficient of skin friction to decrease along the x direction, and the skin friction coefficient is raised along the y direction.

“…Abraham [27] has investigated the problem of Rayleigh-Benard convection in a micropolar ferromagnetic fluid layer permeated by a uniform magnetic field for stress-free boundaries. Reena and Rana [28,29] have studied the some convection problems on micropolar fluids saturating a porous medium. Recently, Thermal instability problem in a rotating micropolar ferrofluid has also been considered by Qin and Kaloni [30] and Sunil et al [31], and references therein.…”

The onset of ferromagnetic convection in a micropolar ferromagnetic fluid layer heated from below in the presence of a uniform applied vertical magnetic field has been investigated. The rigid-isothermal boundaries of the fluid layer are considered to be either paramagnetic or ferromagnetic and the eigenvalue problem is solved numerically using the Galerkin method. It is noted that the paramagnetic boundaries with large magnetic susceptibility χ delays the onset of ferromagnetic convection the most when compared to very low magnetic susceptibility as well as ferromagnetic boundaries. Increase in the value of magnetic parameter M₁ and spin diffusion (couple stress) parameter N₃ is to hasten, while increase in the value of coupling parameter N₁ and micropolar heat conduction parameter N₅ is to delay the onset of ferromagnetic convection. Further, increase in the value of M₁, N₁, N₅ and χ as well as decrease in N₃ is to diminish the size of convection cells.
