Numerical simulation of a nonlinear coupled differential system describing a convective flow of Casson gold–blood nanofluid through a stretched rotating rigid disk in the presence of Lorentz forces and nonlinear thermal radiation

Abstract

Extensive analysis has recently been presented on the applications of nanofluids in heat transfer developments. The primary concern of this work is to excogitate the flow features of blood flow with the inclusion of gold plated nanoparticles. In this regard, the Casson fluid model was adopted to simulate the transportation of blood flow. The momentum features of flowing fluid are divulged by incorporating magnetization and porosity aspects whereas thermal attributes of concerned flow are anticipated under nonlinearized radiating thermal flux. Formulated governing expressions are transmuted into the system of the nonlinearized ordinary differential structure by implementing appropriate conversion. The solution is headed by implementing an efficient build in routine renowned as bvp4c based on the finite differencing. The impacts of the involved parameters on the resulting dimensionless profiles are discussed thoroughly. The results indicating that the velocity in radial direction declines with augmenting the nanoparticle volume fraction, while the velocity in the azimuthal direction and the temperature upsurge. Besides, the velocities in the radial and azimuthal directions augment due to rotation parameter and the temperature shrinks.
