Summary: The impact of thermal stratification and thermally radiative flow of carbon nanotubes on a Riga plate with injection/suction and heat generation/consumption is investigated. The two varieties of base fluids, like, water and glycerin with single-wall nanotubes and multi-wall carbon nanotubes, are incorporated in this investigation. The consequences of the physical parameters on fluid velocity, fluid temperature, skin friction coefficients and local Nusselt number are explained through tables, graphs and charts. It is detected that the fluid velocity in both directions diminishes when raising the suction/injection and velocity slip parameters. The fluid temperature downturns when enhancing the suction/injection and stratification parameters. The surface shear stress suppresses when increasing the Forchheimer number. The radiation parameter leads to strengthening the heat transfer gradient.

Summary: This research work explores the thermal and mass transport phenomena for a time-dependent Maxwell fluid flow in the presence of Cattaneo-Christov concept. The study analyzes the Maxwell fluid flow through stretching cylinder and sheet with effects of Brownian motion, non-uniform heat source/sink, thermophoresis, and variable thermal conductivity. The theoretical analysis of the modeled system is explored using HAM, with graphical representation of the impacts of fixed constraints on velocity, thermal, and concentration functions. The conclusion highlights the increase in velocity profile for Newtonian fluid compared to non-Newtonian fluid (Maxwell), while temperature and concentration distributions increase quickly for non-Newtonian fluid compared to Newtonian fluid, with the presence of Maxwell and magnetic parameters increasing the size of the trapping bolus.

Summary: The investigation analyzed the flow and heat transfer behavior of a non Newtonian fluid subject to an externally inclined magnetic field. The study revealed that the increase in magnetic field strength has an opposite effect on fluid velocity and temperature, while factors such as thermal relaxation time and curvature parameter play a role in controlling the rate of heat transportation. Additionally, the angle of inclination of the magnetic field affects the fluid flow in a reverse manner.

Summary: This article examines the magneto-bioconvective properties of nanofluid flow through a rotating cone using the Cattaneo-Christov heat flux model. The effects of cross diffusion, porous medium, Stefan blowing, and Navier slip are analyzed, and the governing equations are transformed into a system of self-similar ordinary differential equations. A parametric study is conducted to investigate the impact of various parameters on different fields, such as motile microorganisms density, nanoparticle concentration, and temperature. The results show that temperature decreases with increasing thermal relaxation parameter gamma, and an increase in magnetic parameter M leads to a decrease in energy field.

Summary: This article investigates the convective boundary layer flow of ternary hybrid nanofluid (water-based graphene-CNT-Silver) over a curved stretching sheet with activation energy, considering the non-Fourier heat flux model. The results reveal the influence of various parameters on thermal, concentration, and velocity profiles. The heat transport in ternary hybrid nanoliquid increases with higher thermophoresis and Brownian motion parameters, while the Biot number positively affects the thermal profile and the Schmidt number and Stefan blowing parameter values reduce mass transport.

Summary: This study investigates a hybrid nanofluid consisting of a mixture of copper (Cu) and gold (Au) nanoparticles with engine oil, and examines its thermal characteristics. The results show that the Hall effect and thermal radiation have opposite effects on fluid temperature, and nonuniform heat sources can increase the fluid temperature. It is observed that the lower disk has a higher heat transfer rate than the upper disk for a radiation parameter of Rd=0.5, while the upper disk has a lower heat transfer rate than the lower disk for a stratification parameter of S=0.2. The reliability of the proposed model is also verified in the article.

Summary: In this paper, we study the split feasibility problem with multiple output sets in Hilbert spaces. We propose two new self-adaptive relaxed CQ algorithms which involve computing of projections onto half-spaces instead of computing onto the closed convex sets, and it does not require calculating the operator norm. We establish a weak and a strong convergence theorems for the proposed algorithms. We apply the new results to solve some other problems. Finally, we present some numerical examples to show the efficiency and accuracy of our algorithm compared to some existing results. Our results extend and improve some existing methods in the literature.

Summary: This study provides a comprehensive assessment of three-dimensional Jeffery fluid flow under the significances of thermal radiation and magnetohydrodynamics. The results revealed that the motion of the Jeffery fluid decreases with increasing porosity term but increases with the rising influence of wall thickness factor. The velocity curve decreases in both x and y directions with the increasing values of Darcy-Forchheimer and magnetic field factors. Furthermore, the temperature curve intensifies with the addition of porosity factor and Deborah number, while lessens with the rising influence of power index.

Summary: This article investigates the flow of a hybrid nanofluid over a three-dimensional stretching surface, influenced by thermal radiation, chemical reaction, and a variable thermal source/sink. The equations governing the fluid behavior have been transformed to a dimensionless form and solved using the homotopy analysis method. The results show that the velocity of the hybrid nanofluid decreases along the primary direction and increases along the secondary direction as the ratio parameter increases. The temperature characteristic is enhanced with greater values of nonlinear thermal radiation and source/sink factors, while the concentration profile is adversely affected by the chemically reactive factor and Schmidt number. A comparative analysis with published results shows close agreement, with the MoS2 + MgO/H2O hybrid nanofluid exhibiting faster temperature and concentration increases compared to MoS2/H2O and MgO/H2O nanofluids.

Summary: In recent years, the interest in diathermal oils has grown due to their many industrial applications. The aim of this study is to develop a new fractal-fractional model to analyze the thermal performance of an oil-based tripartite hybrid nanofluid for channel flows. Different nanoparticles are dispersed in engine oil to obtain a tripartite hybrid nanofluid, and the impacts of shape factor on thermal performance are evaluated. The mathematical model involves a fractal-fractional derivative and is solved using classical and fractal Laplace transforms. The results show that the fractal-fractional approach provides a better understanding of memory effects and dispersing three types of nanoparticles in engine oil enhances its heat-conduction capacity by 9.58%.
