Nanofluids are smart fluids, which very useful for heat and mass transfer enhancement. They much used in industrial, transportation, biomedical, electronics fields. In the present research, we examine nanofluid flow across a curved stretching sheet (CSS). Also, this work’s noteworthy originality is its discussion of impacts physical parameters on ternary hybrid transfer. Furthermore, simulation considers nanofluids with water as base fluid. The Koo–Kleinstreuer–Li (KKL) model examines viscosity effective thermal conductivity fluid suspended nanoparticles. governing equations momentum temperature transformed into ordinary differential (ODEs) by similarity transformations. These then solved using Secant iteration method combined Runge–Kutta–Fehlberg (RKF) integration scheme shooting technique. Through graphs tables, influences relevant non-dimensional presented analyzed. findings show that an increase curvature parameter Biot number to gradient. Streamline profiles various values magnetic also analyzed through figures. We believe research has significant implications biomedical devices pharmaceutical preparation sciences. Some them high cooling processes, paints, space technology, medicines, cosmetics, conductive coatings, bio-sensors, name few.

The force of attraction between two masses increases as gravity increases. Gravity is very important mechanism for mass transfer characteristics across the inclined shape. significant purpose current study to examine amplitude in under reduced gravity-driven flow. impact heat source/sink on periodic mixed convective flow plate has been evaluated. oscillatory rate and transmission are explored at three angles π/6, π/4 π/3. assumed maximum temperature difference. governing dimensional model transformed into non-dimensional equations with appropriate scaling variables. again non-oscillatory, real imaginary parts. For smooth coding, primitive formulation used finite difference method change forms algebraic system. solved Gaussian elimination scheme display velocity field, distribution concentration numerically. ±δ, Rg, buoyancy variable λT, modified factor λC, Prandtl Pr, gravitation Schmidt Sc oscillating behavior shear stress, fluctuating transfer, secured. It found that fluid each parameter source +δ=0.4. can be seen Rg sink −δ=0.3. shearing stress +δ obtained oscillation ±δ Rg=1.2.

Thermal analysis is carried out on the flow of Sisko fluid over Riga curved stretching sheet in presence Lorentz force and heat energy application. Heat transmission supported by considering Prescribed Flux (PHF) Surface temperature (PST). This study explores role fluids solving various bioengineering problems opportunities for clinical measures to treat blood-related diseases. It has been concluded that medical science requires model be explored understanding blood transfusion problems. Mathematical modeling yields complex partial differential equations, which are transformed into ordinary equations via appropriate transformations. The outcome these parameters observed best match suits our defined boundary conditions. Numerical solutions obtained using Matlab function bvp4c, setting default tolerance better approximate solutions. Impacts associated profiles elaborated with tables graphs. Temperature (PST) reduces enrichment Pr. A higher Prandtl number indicates disturbances spread more slowly through fluid. means near surface takes longer reach equilibrium bulk temperature, leading a decrease temperature. become declines enlarging values determines ratio momentum diffusivity thermal diffusivity. value lower diffusivity, can result thicker layer.
