Numerical computation of magnetic field over a TiO2 Cu/CuO-water based hybrid nanofluid flow with viscous dissipation and thermal radiation

Abstract

This study intends to investigate the hybrid nanofluids with viscous dissipation and thermal
radiation effects of the magnetic field. The consequences of viscous dissipation and thermal
radiation on the transport of Cu ? T iO2/water and CuO  T iO2/water were investigated.
Magnetic fields create a hybrid nanofluid with varying viscosity. By including suitable symmetry variables, the fluid model is converted into ordinary differential equations. For the
numerical simulation, we employ the bvp4c package in MATLAB. The evaluation’s findings
are laid out graphically in tables and charts. Various values of crucial parameters such as
variable viscosity, magnetic field, viscous dissipation, and nanoparticle volume fraction are
investigated better to grasp the nature of the problem’s energy flow and energy transfer
characteristics. It was revealed that raising the magnetic field and the suction/injection
parameters reduces velocity. While the fluid velocity remains constant, the temperature distribution changes as the viscous dissipation, magnetic field, and thermal radiation parameters
increase.
