Summary: This study investigates the entropy generation in peristalsis caused by different nanoparticles. Mathematical equations and models are used to analyze the problem, considering variables such as viscosity, thermal radiation, viscous dissipation, heat generation/absorption, and mixed convection. The equations are simplified and dimensionless using a lubrication technique. The resulting system of equations is solved numerically, and the results are presented in graphs. The findings indicate that high volume fraction leads to a decrease in velocity and temperature, while temperature-dependent viscosity decreases entropy and increases the Bejan number.

Summary: This paper examines the squeezing flow of hybrid nanofluid within two parallel disks. The study analyzes entropy generation by using the second law of thermodynamics and estimates the behavior of a porous medium using Darcy's model.

Summary: This study investigates the impact of thermal radiation on the inertial drag force of a hybrid nanoliquid flow in three-dimensional geometry, specifically in relation to external heat generation and absorption. It is found that the shape of particles, whether symmetric or non-symmetric, affects the velocity due to the direction of drag. Additionally, the interaction between the conducting fluid and magnetic field through a permeable medium on an expanding surface influences the flow phenomenon. The results have implications for blood dialysis in artificial kidneys, blood flow in capillaries, and engineering filter design. The problem is transformed into a non-dimensional form for implementation of similarity rules and solved using a shooting-based Runge-Kutta fourth-order technique. The simulations show entropy generation and the Bejan value, and graphical results for momentum, temperature, entropy, and the Bejan number are presented. The inclusion of volume concentration in association with the magnetic field restricts the axial and transverse velocity profiles, and an enhanced Brinkman number increases entropy generation significantly. The numerical validation demonstrates good correlation with earlier investigations in specific cases.

Summary: This study examines the mathematical formulations of hybrid nanoliquid filled with thermal radiation, Cattaneo-Christov heat theory and melting phenomenon in a rocket engine nozzle. By transforming the governing equations into a system of nonlinear ODEs using similarity transformations, the outcomes are obtained using the bvp4c method in MATLAB software, with physical flow characteristics shown against velocity, temperature, and entropy generation profiles. Velocity decreases with higher volume fraction of nanoparticles and melting parameter, while the thermal field decreases with variations in thermal relaxation and melting parameters, and increases with higher Biot number. The entropy generation profile increases with higher Reynolds number and Brinkman parameter, with this study being the first attempt to characterize melting phenomena and Cattaneo-Christov heat theory in a rocket engine nozzle using hybrid nanoparticles and kerosene as a base fluid.

Summary: This article presents a comparative study of magnetohydrodynamics stagnant point flow in hybrid nanofluid using the extended versions of the Yamada-Ota model and Xue model. The study considers a time-dependent and thermally radiative two-dimensional flow with a stretchable/shrinking permeable sheet. The hybrid nanofluid is formulated by suspending Aluminum Oxide Al2O3 and Copper Cu nanoparticles in water. The nonlinear dimensionless system of ordinary differential equations is solved numerically using the bvp4c methodology. The study finds that the heat transfer rate is higher in the Yamada-Ota model compared to the Xue model, and increasing the stretching parameter enhances the velocity field but deteriorates the temperature distribution.

Summary: In this study, a mathematical computational analysis was conducted on mixed convection nanofluid (CuO-water) flow in a lid-driven parallelogram enclosure with corrugated walls. The flow dynamics were investigated using the finite element method, and the outcomes in terms of isotherms, streamlines, and line graphs were analyzed against various emerging parameters. The results showed that at lower Richardson numbers, the flow exhibited forced convection, while at higher Richardson numbers, the flow transitioned to free convection. Additionally, maximum heat transfer was observed when a magnetic field was applied perpendicular to the flow and at maximum amplitude of wall undulations.

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.
