Finite Difference Computation of Au-Cu/Magneto-Bio-Hybrid Nanofluid Flow in an Inclined Uneven Stenosis Artery

The present study addresses the fluid transport behaviour of the flow of gold (Au)-copper (Cu)/biomagnetic blood hybrid nanofluid in an inclined irregular stenosis artery as a consequence of varying viscosity and Lorentz force. The nonlinear flow equations are transformed into dimensionless form by using nonsimilar variables. The finite-difference technique (FTCS) is involved in computing the nonlinear transport dimensionless equations. The significant parameters like angle parameter, the Hartmann number, changing viscosity, constant heat source, the Reynolds number, and nanoparticle volume fraction on the flow field are exhibited through figures. Present results disclose that the Lorentz force strongly lessens the hybrid nanofluid velocity. Elevating the Grashof number values enhances the rate of blood flow. Growing values of the angle parameter cause to reduce the resistance impedance on the wall. Hybrid nanoparticles have a superior wall shear stress than copper nanoparticles. The heat transfer rate is amplifying at the axial direction with the growing values of nanoparticles concentration. The applied Lorentz force significantly reduces the hybrid and unitary nanofluid flow rate in the axial direction. The hybrid nanoparticles expose a supreme rate of heat transfer than the copper nanoparticles in a blood base fluid. Compared to hybrid and copper nanofluid, the blood base fluid has a lower temperature.

Automated summary

This study investigates the fluid transport behavior of gold-copper/biomagnetic blood hybrid nanofluid in an inclined irregular stenosis artery, considering varying viscosity and Lorentz force. The results show that Lorentz force significantly reduces the velocity of the hybrid nanofluid, while increasing Grashof number enhances blood flow rate. Increasing the angle parameter reduces the resistance impedance on the wall, and hybrid nanoparticles have higher wall shear stress than copper nanoparticles. Heat transfer rate increases with increasing nanoparticle concentration, and the applied Lorentz force significantly reduces the flow rate of the hybrid and unitary nanofluid. The hybrid nanoparticles exhibit a superior rate of heat transfer compared to copper nanoparticles in a blood base fluid, and the blood base fluid has a lower temperature.
