An exact solution for unsteady three-dimensional magnetohydrodynamic Casson flow of dusty nanofluid over a porous stretching sheet

The unsteady three-dimensional (3D) Casson flow of a nanofluid containing dust particles over a porous, linearly stretching sheet in the presence of an external magnetic field is studied.  It is assumed that the sheet is stretched in both directions along the $xy$ plane.  The governing equations of the two-phase model are partial differential equations that are transformed into ordinary equations using similarity transforms.  The nanofluid is a suspension of water-based nanoparticles.  In this study, we look at how nanoparticle size affect the properties of dusty nanofl

Numerically investigating the effects of slip and thermal convective on nanofluid boundary layer past a stretching/shrinking surface

The study is focusing on the steady boundary layer flow, heat and mass transfer passing through stretching/shrinking sheet immersed in nanofluid in the presence of the second order slip velocity and thermal convective at the boundary.  The governing partial differential equations are converted into ordinary differential equations by applying the similarity variables before being solved computationally using bvp4c function in Matlab software.  The results of skin friction, heat transfer as well as mass transfer coefficient on the governing parameter such as the first ord

Effects of Brownian Motions and Fractal Structure of Nanoparticles on Natural Convection

The study simulated heat transfer in alumina-water nanofluid in a natural convection flow and Rayleigh-Benard configuration considering the Brownian motions and fractal structure of the nanofluids. The simulations were based on a two-dimensional, Eulerian-Eulerian method. Many simulations have been performed to examine the effect of aspect ratio, heat flux, and para-meters related to the structure of the nanoclusters including size, fractal dimension, and volume fraction on the natural convective heat transfer coefficient.

Radiative flow of magnetic nanofluids over a moving surface with convective boundary condition

The influence of convective boundary conditions and heat radiation on magnetic nanofluids (MNFs) flowing through a permeable moving plate is investigated numerically in this study.  The governing partial differential equations (PDEs) are transformed into ordinary differential equations (ODEs) using suitable similarity variables.  The ODEs are solved by implementing the built-in solver in Matlab called bvp4c.  The stability analysis has supported our initial presumption that only the first solution is stable.  The thermal performance between cobalt ferrite nanofluid and manganese-zinc ferrit

Numerical exploration of mixed convection heat transfer features within a copper-water nanofluidic medium occupied a square geometrical cavity

The phenomenon of mixed convection heat transfer in a homogeneous mixture is deliberated thoroughly in this study for cooper-water nanofluids flowing inside a lid-driven square cavity.  By adopting the Oberbeck-Boussinesq approximation and using the single-phase nanofluid model, the governing partial differential equations modeling the present flow are stated mathematically based on the Navier--Stokes and thermal balance formulations, where the important features of the scrutinized medium are presumed to remain constant at the cold temperature.  Note here that the density quantity in the bu
