In this research article, we investigated a comprehensive analysis of time-dependent free convection electrically and thermally conducted water-based nanofluid flow containing Copper and Titanium oxide (Cu and TiO 2 ) past a moving porous vertical plate. A uniform transverse magnetic field is imposed perpendicular to the flow direction. Thermal radiation and heat sink terms are included in the energy equation. The governing equations of this flow consist of partial differential equations along with some initial and boundary conditions. The solution method of these flow interpreting equations comprised of two parts. Firstly, principal equations of flow are symmetrically transformed to a set of nonlinear coupled dimensionless partial differential equations using convenient dimensionless parameters. Secondly, the Laplace transformation technique is applied to those non-dimensional equations to get the close form exact solutions. The control of momentum and heat profile with respect to different associated parameters is analyzed thoroughly with the help of graphs. Fluid accelerates with increasing Grashof number (Gr) and porosity parameter (K), while increasing values of heat sink parameter (Q) and Prandtl number (Pr) drop the thermal profile. Moreover, velocity and thermal profile comparison for Cu and TiO 2 -based nanofluids is graphed.

In this paper, numerical investigations are presented for hybrid nanoparticle migration and free convection heat transfer of two kinds of nanofluids in a micromixer at the fixed propeller condition. The inner blades and outer crust of the micromixer are kept at constant hot and cold temperatures, respectively. Two kinds of hybrid nanofluids, TiO2‐CuO water and ethylene glycol‐(MoS2‐SiO2), are considered. The governing equations including velocity, pressure, temperature formulation, and nanoparticle concentrations are solved by a partial differential equation solver based on the Galerkin finite element method. The results are discussed based on the governing parameters, such as nanoparticle volume fraction, thermal and solutal Rayleigh numbers. The average Nusselt number was found to increase with the increasing nanoparticle volume fractions. Also, increasing the thermal Rayleigh number enhanced heat transfer while the solutal Rayleigh number has an insignificant effect on it. More importantly, increasing the thermal Rayleigh number assisted avoiding the agglomeration of nanoparticles around the blades and ensured more uniform nanoparticle distribution.

Features of melting heat transfer as well as homogeneous-heterogeneous reaction in thermally stratified stagnation flow of Eyring-Powell fluid along with heat generation/absorption effects are explored in this article. Fluid flow is examined over a sheet of variable thickness in the presence of stretching phenomena. Variable strength of magnetic field is considered normal to the flow field. Suitable transformations are introduced for the sake of conversion of partial differential equations to ordinary differential equations. Homotopic method is utilized to tackle highly nonlinear problem and series solutions are attained. Behaviors of relevant parameters are portrayed for velocity, thermal and concentration distributions. Graphical results reveal that the concentration profile enhances for higher Schmidt number while it exhibits recessive behavior for increment in homogeneous reaction parameter. Larger values of heterogeneous reaction parameter result in intensified concentration field. Velocity field declines as a result of increment in fluid parameters  as well as  * .
