Unsteady MHD carbon nanotubes suspended nanofluid flow with thermal stratification and nonlinear thermal radiation

Abstract

This exploration studies the flow of magnetohydrodynamic (MHD) nanofluid amid two extendable rotating disks with carbon nanotubes suspension in the Ethylene glycol (CH2OH)2which is taken as base fluid. The flow is affected by Hall current and Cattaneo-Christov (CC) heat flux. The uniqueness of the presented problem is exhibited by the addition of thermal stratification, homogeneous-heterogeneous reactions (HH) and nonlinear thermal radiation. The dimensionless system of differential equations is achieved by engaging the similarity transformations from the envisioned mathematical model in partial differential equations. The solution of the proposed system is obtained by MATLAB software function bvp4c. The articulate discussions accompanied physical scenarios of the graphical illustrations are also given. The validation of the presented model is also considered by comparing with a limiting case of already studied problem. An outclass harmony is achieved here. The results obtained show that escalating thermal stratification will lowers the thermal profile.
