Summary: Double-diffusive convection in nanofluid flow with variable heat capacity is investigated in rectangular and inclined walls. The focus is on the appropriate geometrical structure and coolant types to ensure effective heat transport in engineering systems. The well-known Buongiorno model is used and the flow is simulated in the upper half channel. The velocity, temperature, and concentration profiles are studied in the presence of different parameters, and the pressure, skin friction, and rates of heat and mass transfer are determined against these parameters at the upper wall of the channel.

Summary: This paper analyzes the effect of wall slip on the fully developed reverse mixed convection of Jeffery nanofluids between two inclined parallel plates. By utilizing three different shapes of nanoparticles, it is found that wall slip significantly affects flow reversal. Furthermore, the paper provides theoretical support by analyzing the effect of physical factors on velocity and temperature distributions.

Summary: The main objective of this study is to investigate the inclined microchannel flow of a Casson nanofluid based on sodium alginate (SA) under a few stresses. The generalized fractional model is solved using the Laplace and Fourier integral transformations, and the parametric influence of other physical elements is considered. Results show that skin friction and Nusselt number can be enhanced by adding nanoparticles, and the fractional derivative makes the study more realistic.

Summary: The objective of this research is to enhance heat transfer and reduce friction by analyzing different nanofluids on a surface. The results show that silver-water nanofluid has a higher heat transfer rate. The findings are validated by comparing them to previous studies and suggest more frequent utilization of nanofluids.

Summary: This study investigates the fluid transport behavior of gold-copper/biomagnetic blood hybrid nanofluid in an inclined irregular stenosis artery, considering varying viscosity and Lorentz force. The results show that Lorentz force significantly reduces the velocity of the hybrid nanofluid, while increasing Grashof number enhances blood flow rate. Increasing the angle parameter reduces the resistance impedance on the wall, and hybrid nanoparticles have higher wall shear stress than copper nanoparticles. Heat transfer rate increases with increasing nanoparticle concentration, and the applied Lorentz force significantly reduces the flow rate of the hybrid and unitary nanofluid. The hybrid nanoparticles exhibit a superior rate of heat transfer compared to copper nanoparticles in a blood base fluid, and the blood base fluid has a lower temperature.

Summary: This research investigates natural convection heat transfer in a nanofluid under a magnetic field. The addition of nanoparticles improves the heat transfer rate, while volumetric radiation increases the Nusselt number and the generated entropy. Furthermore, as the magnetic field angle increases, the heat transfer rate decreases, but the Rayleigh number enhances natural convection heat transfer and entropy generation.

Summary: This article examines the effects of heat transfer in a compressible time-dependent laminar flow passing through two distinctly positioned elliptic cylinders. The study includes numerical solutions for the Navier-Stokes equations, mesh creation, and analyses of velocity, pressure, temperature distribution, and surface volume of fluid. The results indicate maximum velocity around the elliptic cylinder boundaries, maximum pressure distribution around the cylinders, and maximum heat transfer coefficient at upper and lower boundaries.

Summary: This study investigates the flow characteristics of a water-based hybrid nanofluid consisting of silver and alumina nanoparticles past a spinning disk. The effects of Brownian motion, activation energy, magnetic field, and thermophoresis are taken into account. The partial differential equations (PDEs) are transformed into ordinary differential equations (ODEs) through suitable correspondence transformations. The modeled equations are solved using a semi-analytical method known as HAM. Graphical representations of the nanofluid and hybrid nanofluid profiles are used. The findings show a decrease in the radial and tangential velocities of the nanofluids and hybrid nanofluid with an increase in the magnetic factor. The hybrid nanofluid exhibits higher growth and better thermal conductivity than the nanofluids due to the magnetic factor.
