Summary: This article examines the numerical estimation of double-diffusive peristaltic flow of a non-Newtonian Sisko nanofluid through a porous medium in a horizontal symmetric flexible channel. Various factors such as Joule heating, nonlinear thermal radiation, viscous dissipation, and heat generation/absorption are taken into consideration, along with the effects of the Brownian motion and thermophoresis coefficients. The study utilizes the long wave approximation to transform the system of partial differential equations into a system of ordinary differential equations, which are then solved numerically using MATLAB's fourth-order Runge-Kutta method. The results highlight the impacts of different parameters on the velocity, temperature, solutal concentration, nanoparticles volume fraction distributions, and pressure gradients within the fluid.

Summary: The aim of this work is to investigate the relationship between the Soret and Dufour parameters in non-uniform channels for magneto Oldroyd 4-constant nanofluids. Numerical modeling of convective double diffusion in Oldroyd 4-constant nanofluids under induced magnetic flux is explored. A low finite Reynolds number and a long wavelength are used to simplify the nonlinear partial differential equations. Numerical methods are applied to solve the reduced differential equation, and exact solutions for nanoparticle, temperature, and concentration are computed. The results show the significance of different physical parameters, including the effect of Soret number and Brownian motion parameter on the concentration of nanosolid particles, as well as the transformation of molecular kinetic energy into thermal energy during the micro-mixing process of nanoliquids and the increase in the magnetic force function due to enhanced electric field and magnetic Reynolds number.

Summary: This study developed a thermal insulation composite material using buffing dust-laden tanning waste mixed with polystyrene and a blowing agent, aiming to promote resource recovery and a circular economy. The composite material exhibited good thermal conductivity, compression strength, density, and water absorption compared to conventional insulation panels. The addition of buffing dust reduced the thermal conductivity of polystyrene by 10%. The composite material also showed thermal stability and the presence of functional groups. Overall, this work not only solved energy consumption issues but also contributed to environmental protection and air pollution reduction through recycling and reusing buffing dust waste as thermal insulation material.

Summary: This paper presents a comprehensive study on the mathematical modelling and numerical simulation of non-Newtonian blood flow in an idealized stenosed artery. The results show that the non-Newtonian nature of the fluid model significantly influences flow dynamics, with a greater degree of stenosis leading to higher velocity and pressure drop. Wall shear is substantially larger in stenotic passages, and the severity of stenosis is directly related to this increasing behavior.

Summary: This study investigates the influence of hybrid nano-fluid on heat transport in a semi-annular channel using numerical methods. The hybrid nano-fluid consists of a liquid water with a suspension of SWCNT and MWCNT. Constant heat fluxes are applied to the channel walls. The finite volume approach is used to solve the governing equations. The results show that heat transport decreases as the volume fraction of MWCNT increases. The heat transfer from the walls to the fluid is affected by the curvature of the walls. The study provides velocity contours, isotherms, and local Nusselt number distributions for certain volume fractions of nanoparticles. It is discovered that walls with smaller curvature have stronger convection heat transfer. The pressure increases with the increase of nanoparticle volume percentage.

Summary: This article investigates the modeling and numerical simulation of Magnetohydrodynamic (MHD) buoyancy driven convection flow in a differentially heated, square enclosure. Numerical solutions are computed for different values of Rayleigh number ranging 103 < Ra < 107 and Hartmann number ranging 0 < Ha < 40. Comportment of MHD free convection heat flow from transient to steady state is numerically examined for a period of 0 to 1 s. It is seen that with increasing values of Rayleigh number there is increase in local Nusselt number distribution on heated side of the cavity, while velocity distribution in the flow domain decreases with increasing Hartmann number.

Summary: The research presents the outcomes of partial slip on double-diffusive convection of Johnson-Segalman nanofluids in an asymmetric peristaltic path with the effect of inclined magnetic field. The mathematical formulation of Johnson-Segalman nanofluids with double-diffusive convection and inclined magnetic field is also discussed. A lubricant approach is applied to simplify the extremely nonlinear partial differential equations. Numerical calculations are obtained for various hydro-mechanical parameters and their effects on velocity, temperature, pressure rise, and concentration functions are evaluated graphically. Slip effect in the channel causes fluid particles to stray and slow down the fluid velocity, while increased thermophoretic effects and Brownian motion lead to rapid movement of nanoparticles and significantly raise the temperature.
