Because of their unique intrinsic physical and chemical properties, carbon nanotubes (CNT) are being used in biological biomedical applications. The current study proposes a mathematical model to analyze the effect interfacial nanolayers on heat mass transfer processes for nanofluid flow. Furthermore, presence fluid (non-Newtonian fluid) with reaction is investigated using porous surfaces. uniform transverse magnetic flux was also included study. Using similarity transformation, nonlinear partial differential equation reduced set ordinary equations. A phase simulation based Brownian thermophoresis factors have been developed this problem. Optimal nanoparticles range 2–8% significant thermal conductivity as well performance blood flow system. numerical procedure supported shooting method, resulting desired accuracy. Utilization Cason parameter under nanolayer has horrendous results. increase thickness, h = 3–9 nm, enhanced effective significantly.

This work inspects the thermal transportation of magnetohydrodynamic Casson trihybrid nanofluid flow over a convectively heated bidirectional elongating sheet. The is considered as three dimensional passing sheet, which placed in porous medium. effects radiations and space- thermal-dependent heat sources are used energy equations, while magnetic momentum equations. Appropriate variables have been to convert modeled equations into dimensionless form, then solved using homotopy analysis method. In this work, it uncovered that both primary secondary velocities weakened with an upsurge porosity factors. augmented growth thermal- space-dependent source factors Biot number. convergence method ensured through ℏ-curves. results investigation also compared existing literature fine agreement among all validation model work.

The current study explores the flow of a Jeffrey nanofluid with impact non-uniform heat source/sink and magnetic effects over stretching sheet by accounting for pollutant's transient dispersion after being released from source outside system. need to enhance efficiency prospective future technologies, including exchangers, solar collectors nanoscale solid particles suspended in base fluid, powered engines, pharmaceutical procedures, hybrid microelectronics, has grown recently. Graphene is treated as nanoparticle NaAlg liquid. To emphasize thermal integrity that now taken into consideration, influence diameter liquid–solid interfacial layer also shown at molecular level. modeled equations are transformed ordinary differential means appropriate similarity transformations. Probabilists' Hermite polynomial collocation technique employed solve these nonlinear dimensionless ODEs, graphical representations created certain significant values underlying physical parameters model. result reveals Deborah number increases, velocity upsurges but temperature declines. A rise concentration observed when local pollutant external variation parameter rises. enhanced advanced parameters.
