Summary: Heat transfer is crucial in industries and a new nanofluid called hybrid nanofluid is being used to enhance heat transfer capabilities. This research investigates the characteristics of steady hybrid nanofluid flow and thermal transport over a slippery surface, taking into account various factors such as nanosolid particle shapes, material porosity, heat source, viscous dissipative flow, and radiative flux. The noteworthy finding is that the thermal transmission level of the hybrid nanofluid (SiO2-Cu/EO) is higher compared to traditional nanofluids (Cu-EO), with lamina-shaped elements demonstrating higher thermal conductivity in the boundary-layer.

Summary: PTSCs are commonly used in solar-thermal applications to achieve high temperatures. This study focused on determining the entropy generation when P-ENF flows across porous media on a horizontal plane under thermal jump circumstances. The research found that changing the permeability parameter affects the fluid properties, which in turn impacts thermal efficiency. Under certain conditions, there is a correlation between the increase in heat transport rate and the decrease in entropy production.

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: In dire situations, heat and momentum transmission in nanoparticle systems and non-Fourier heat conduction exhibit non-linear and nonlocal behavior. This study investigates the mechanisms of heat and mass transfer in non-Newtonian fluid flow between inclined planes with porous walls, incorporating a Carreau rheological model. The proposed model incorporates the Cattaneo heat flux to describe anomalous heat and mass transport, considering radiation flux, Brownian diffusion, and thermophoresis. Numerical simulations show that flow reversal only occurs in the divergent domain, and inertial forces dominate the transport process in the convergent domain.

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 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 paper investigates the existence and approximate controllability of Atangana-Baleanu-Caputo (ABC) fractional order neutral delay integrodifferential stochastic systems with nonlocal conditions. The system is transformed into an equivalent fixed point problem using an integral operator, which is analyzed for boundedness, continuity, and equicontinuity. The compact multivalued function of the operator is ensured by Arzela-Ascolli theorem, and the existence of the mild solution is proved using Martelli's fixed point theorem. Approximate controllability results are developed based on fixed point theorem, Dunford-Pettis theorem, and f-resolvent operators, and an example is provided to validate the theoretical results.

Summary: This study investigates the flow model of hybrid nanofluids (gold-silver/engine oil) over a stretched cylindrical surface and a sheet in a permeable medium. The novelty lies in considering surface-catalyzed reaction and homogeneous-heterogeneous reactions to accelerate chemical reactions. The heat transport phenomena are enhanced with the support of Joule heating, heat absorption/generation, and the convective heat boundary condition. Ordinary differential equations are obtained using boundary layer theory and numerically solved using the Keller box method. The results show that the thermal profile enhances while the velocity field reduces for different magnetic parameter estimates, and the fluid concentration decreases when the surface-catalyzed parameter increases.

Summary: Scientists explored the effect of non-Newtonian fluids on a symmetric stretchable sheet and found diverse influences with wide applications. They proposed a model considering various effects and used novel tetra hybrid nanoparticles to examine the thermo physical behavior. The partial differential equations were transformed into ordinary differential equations and solved numerically. The findings showed that tetra hybrid nanofluids had a higher heat transfer Nusselt number, the fluid velocity decreased with Darcy Forchheimer effect, and the temperature increased due to thermal radiative variable. The insertion of nanoparticles enhanced flow stability and reduced heat transfer Nusselt number error.

Summary: A novel theoretical ternary hybrid nanofluid (HNF) model is proposed to enhance heat transport. Tri-hybrid nanoparticles made of Au, Ag, and TiO2 are dissolved in blood as the base fluid. The traditional Tiwari and Das HNF model is modified for the tri-HNF situation. The computed outcomes demonstrate that the tri-hybrid nano-fluid (THNF) has better thermal conductivity than HNF. Additionally, it is found that the external magnetic force can regulate velocity, affecting temperature distribution and heat transmission.

Summary: In this paper, we study the existence and optimal control results for second-order Sobolev type delay systems with Clarke's subdifferential type. The existence of a mild solution is established for the proposed second-order delay differential system using the novel ideas of Clarke's subdifferential. The fixed point theorem of condensing multi-valued maps, the strongly continuous cosine family, and the properties of Clarke's subdifferential are used to establish the existence of a mild solution. Moreover, the existence of an optimal control pair governed by the presented system is verified through Balder's theorem. Finally, an example is provided to illustrate the main results.
