Flow behavior of magnetized Casson nanoblood containing penta hybrid nanoparticles through a squeezed arterial channel

In the present research, we have investigated the phenomena related to the heat and mass transfer within a steady flow of nanoblood containing penta hybrid nanoparticles. These nanoparticles are engineered with five distinct functional components confined between two parallel sheets of a vertical arterial channel. Here we have considered a uniform magnetic field as a contributing factor. By similarity substitutions, the model equations expressed as partial differential equations are converted into non-linear ordinary differential equations. The numerical solution of the highly non-linear equations is obtained by using Runge-Kutta-Fehlberg method with the shooting scheme. The analysis comprehensively evaluates various critical parameters such as viscosity coefficient, Casson flow parameter, Hartmann number, thermophoretic parameter, Brownian parameter etc. Computational for the variation in primary velocity, secondary velocity, temperature, concentration, Nusselt number and Sherwood number are presented in graphical/tabular. An increase in wall squeezing intensity enhances the axial flow while diminishing the transverse motion, whereas the Lorentz force exhibits an opposite trend. Greater thermal diffusivity reduces temperature but enriches species concentration, showing dual behavior in heat and mass transfer rates. Higher mass diffusivity weakens concentration levels yet maintains duality in mass transfer characteristics. Enhanced fluid viscosity promotes axial momentum, suppresses secondary flow, lowers temperature, and intensifies species concentration, further highlighting the dual nature of thermal and solutal transport. Overall, the effects of various parameters are comprehensively discussed, revealing that the penta-hybrid nanoblood significantly influences the velocity, heat, and mass transfer characteristics along with the Nusselt and Sherwood numbers.
