Summary: The aim of this paper is to investigate the MHD and radiative flow and thermal characteristics of a non-Newtonian Reiner-Philippoff nanofluid with Brownian and thermophoresis diffusion effects. A unique model is proposed to observe shear thickening and shear thinning properties of the fluid with embedded diffusion implications. The results show that the skin friction coefficient and heat and mass transfer rates are highest for shear-thickening fluid, followed by Newtonian and shear-thinning fluids. The thermophoresis parameter decreases the heat and mass transfer rate, while the Brownian motion parameter increases the mass transfer rate but decreases the heat transfer rate.

Summary: This investigation numerically studied the heat and mass transfer in a rotating porous disk immersed in magnetic nanofluid (C1-20B) using a numerical approach. The effects of various parameters, such as permeability, viscosity variation, rotation, radiation, ferrohydrodynamic interaction, thermophoresis, and Brownian motion, on the flow regimes were analyzed and presented graphically. The results also showed the numerical data for the rate of heat and mass transfer and coefficients of skin friction in tabular form.

Summary: The aim of this study is to investigate the flow, heat and mass transfer in the Blasius flow of a nanofluid on a curved surface. The energy equation is formulated to account for the Joule heating effect and heat generation. The Buongiorno model is used for the nanofluid, and both homogeneous and heterogeneous chemical reactions are considered in the nanoparticle concentration equation. Entropy generation method (EGM) is employed for energy optimization. The mathematical development of the flow problem is done using a curvilinear coordinate system, and the resulting partial differential equations are solved numerically using shooting method and Runge-Kutta integrating scheme. The obtained numerical results are validated using the Keller-box method, and the impacts of various parameters on velocity, temperature, concentration, entropy generation, Bejan number, skin friction coefficient, Nusselt number, and Schmidt number are presented and discussed.

Summary: This study investigates the flow of Casson fluid with homogeneously distributed dust particles streaming through a porous zone in a permeable channel. The flow is oscillatory and subjected to thermal radiation. The channel is under transverse magnetic flux control, with non-uniform temperature and velocity slip at the wall. The variable separation approach is used to obtain the exact analytic solution for the flow fields of fluid and dust particles. The results reveal the effects of suction/injection, magnetic field, thermal radiation, and buoyancy force on the fluid velocity, temperature, rate of heat transport, and friction at the wall surface, as examined and analyzed graphically.

Summary: This article focuses on the consequences of melting heat transfer on the chemically reactive flow of Eyring-Powell liquid flow in a semi-permeable curved channel in the presence of an applied magnetic field. The effects of homogeneous and heterogeneous chemical reactions are considered in the concentration equation, and the characteristics of heat transport phenomena are examined with the application of thermal radiation. Nonlinear ordinary differential equations are obtained through the adoption of a curvilinear coordinates system and appropriate similarity conversions. Numerical simulations are used to estimate the determined velocity and transport equations using the shooting procedure. The influence of pertinent factors on the flow equations, surface drag force, and rate of heat transport is thoroughly discussed through graphs and tables.

Summary: This study investigates the stability of dual solutions for the heat and mass transfer flow of hybrid nanofluid over a stretching/shrinking surface with a uniform shear flow, taking into account thermal radiation, transpiration, and chemical reaction. Gold (Au) and zinc oxide (ZnO) are chosen as nanomaterials and engine oil (EO) as the base fluid. The nondimensional differential equations are transformed into dimensionless coupled differential equations using the similarity transformation technique. The least square method (LSM) is then applied to solve the system analytically and obtain the dual solutions within a specific range of the stretching/shrinking parameter lambda. Stability analysis is performed to determine the stability of the solutions based on the computed eigenvalues. The impacts of various physical parameters on the governing problem are discussed and presented in graphical form.

Summary: This paper investigates the mixed convective peristaltic transport of ternary hybrid nanofluids between two sinusoidally deforming lubricated curved concentric tubes. Titanium, Alumina, and copper nanoparticles are used with blood as the base fluid in this study. The heat equation is also considered with heat generation/absorption. The exact solutions for velocity, temperature, pumping phenomenon, and streamlines are obtained using the separation of variable technique. The results show that the liquid velocity increases near the outer wall of the sinusoidal curved tube but decreases with the peristaltic endoscope for enhancing curvature parameter. The fluid temperature is reduced by increasing the values of the curvature parameter.
