Summary: This analysis investigates the importance of bio-convection for the flow of Carreau nanofluid over a stretched cylinder, considering the contributions of melting phenomenon and chemical reaction. The study examines the thermal flow analysis in terms of convective Marangoni boundary constraints, and takes into account the thermal diffusivity parameter and Brownian motion. The results show that the presence of melting parameter and Weissenberg number enhances the nanofluid velocity, while the velocity profile exhibits the opposite trend for the curvature parameter. An increasing heat transfer pattern is observed for the Biot number and curvature parameter, while the concentration profile decreases with the Marangoni number and Marangoni ratio parameter.

Summary: Solar power is important for meeting energy needs in industry and households. The practical use of solar power is examined by improving the heat diffusion rate of conventional liquid. A hypothetical analysis is conducted for third-grade cylindrical film flow with consideration of MHD, radiation, Ohmic heating, and Cattaneo-Christov heat flux. Water is used as the base liquid with graphene oxide nanoparticles. An exact model is established and solved computationally through suitable comparisons. The use of a parabolic trough solar collector is directly incorporated in the flow model. Comparative analysis is performed on Xue and Maxwell nanomodels, highlighting the enhancement of nanofluid temperature and heat transmission rate.

Summary: This study proposes a new 3D mathematical model to analyze the flow of rotating Eyring-Powell ternary-hybrid nanofluid in solar HVAC systems. The model considers various factors such as solar thermal radiation and activation energy impact. Numerical simulations are performed to investigate the effects of regulating parameters on skin friction, heat, and mass transfer. The results show that the use of ternary nanofluids leads to the highest Nusselt numbers, and the temperature slip and relaxation time parameters tend to reduce the Nusselt number while the radiation parameter enhances it. The study is significant for engineering applications such as metal dying and extrusion processing.

Summary: In this article, the problem of solving a strongly monotone variational inequality problem over the solution set of a monotone inclusion problem in real Hilbert spaces is considered. Two improved methods, which are modifications of the Tseng splitting method, and projection and contraction methods, are presented. These methods are equipped with inertial terms to enhance convergence speed. The strong convergence results of these methods are proved under some standard assumptions on the control parameters. Moreover, strong convergence results are obtained without prior knowledge of the operator norm. Finally, these methods are applied to solve various problems and numerical experiments are conducted to demonstrate their efficiency.
