Summary: This study investigates the combined influence of thermal dissipation and Darcy dissipation on the steady motion of a fully developed mixed convection flow through a vertical composite channel partially filled with porous material. The results show that increasing the Brinkmann number increases the temperature and velocity profiles, while increasing the thickness of the porous medium increases the pressure gradient and increasing the porosity reduces the pressure gradient within the composite channels.

Summary: The study analyzes the mixed convective rheology and second law analysis of (Al2O3-Ag/H2O) hybrid nanofluid flow influenced by magnetic induction effects on a stretching sheet. Results show that a large value of lambda 1 can enhance velocity, entropy generation, and heat transfer rate, while reducing temperature; whereas a large value of delta increases velocity and temperature but decreases heat transport and entropy generation number.

Summary: This work focuses on the analytical analysis of steady flow of nanofluid with viscous dissipation and convective boundary condition. MWCNT and SWCNT are used to describe the nanofluid. A similarity transformation is applied to convert the nonlinear PDE to dimensionless nonlinear ODE. The developed ODE for velocity and temperature profiles is solved using the homotopy asymptotic method. Graphs are used to discuss the results and interpret the effects of several factors. The skin friction and Nusselt number are presented in the form of a table.

The study is novel in considering microscopic effects and the effect of radial stretching on micropolar nanofluid flow.

Summary: This study investigates the flow of nanoliquid over an extendible surface using a micro-rotational approach. Nanotechnology has recently focused on dispersing nanoparticles in liquids to enhance thermal conductivity and energy generation. The study examines energy transfer through a permeable oblique surface, considering Dufour impacts, thermal radiation, viscous dissipative effects, and magnetism forces in porous media. Utilizing the bvp4c computational technique, the study converts the flow expressions into nonlinear differential equations using a suitable similarity conversion. The findings demonstrate that the Dufour and Eckert effects contribute to the increase in temperature profile, while the inclined surface's permeability results in lower velocity curves. This fundamental discovery has significant implications for engineers and scientists working on fluid flow and the development of advanced systems.

Summary: This paper investigates the mixed convection flow of a micropolar fluid in the presence of a magnetic field, with a non-linear stretching sheet through a porous medium. Non-uniform heat generation/absorption and chemical reaction are also taken into consideration. The governing equations are transformed using the similarity transformation and solved using the Homotopy Analysis Method. The effects of various parameters on velocity profiles, angular velocity profiles, temperature profiles, and concentration profiles are graphically presented. Skin friction, Nusselt number, and local Sherwood number coefficients are also determined and shown. The findings are in good agreement with earlier studies, revealing that thermal radiation parameter and material parameter enhance velocity and angular velocity profiles, Biot number and Eckert number significantly increase temperature profiles, chemical reaction parameter reduces concentration profile, and Soret number improves concentration profile. Heat transfer rate increases with thermal radiation parameter and decreases with Biot number for both linear and non-linear stretching.
