Simultaneous heat and mass enhancement in mixed convective flow of power-law fluid using hybrid nanoparticles

Heat conduction and solute diffusion in fluid have been used for modeling of simultaneous heat and mass transportation in non-Newtonian fluid obeying the power-law rheological constitutive model. For thermal and mass transport enhancement, nanoparticles (Cu and Al2O3) are dispersed in a mixture of water and ethylene glycol (EG). Mathematical models with correlations for physical properties are solved numerically via the finite element method (FEM). Wall shear stress on the surface of the pipe is enhanced when the intensity of the magnetic field rises. The wall shear stress reduces as positive buoyancy force increases. However, when the buoyancy force is negative (Gr < 0), the wall shear stress increases. When the Grashof number Gr(Gr > 0) is raised, the heat transfer rate at the pipe's surface tends to rise. Similarly, as the Schmidt number rises, the mass flux rises as well. Numerical outcomes have predicted that the motion of fluid becomes fast as the curvature parameter is increased. Favorable Buoyancy force increases the thickness of momentum boundary layer flow, whereas opposing Buoyancy force is responsible of a decrease in thickness of momentum boundary layer flow. Joule heating is responsible of an increase in the thermal boundary layer. Wall shear stress on the surface of the pipe is enhanced when the intensity of the magnetic field is increased.
