Radiative Darcy-Forchheimer Squeezing Carbon Nanotubes Suspended Nanofluid Flow Between Parallel Disks

Abstract

This study aims to investigate the time dependent squeezing flow of nano-fluid flow comprising carbon-nanotubes (CNTs) of dual nature say single-walled carbon-nanotubes (SWCNTs) and multi-walled carbon-nanotubes (MWCNTs) amidst two parallel disks. The upper disk is moving (towards and away) from the lower stationary and permeable disk. Numerical simulations of the proposed model are conducted accompanied by Cattaneo- Christov (CC) heat flux in a Darcy-Forchheimer permeable media. Additional impacts of homogeneous-heterogeneous (HH) reactions are also taken with melting heat. Relevant transformations procedure is implemented for the transition of partial differential equations to ordinary one. A computer software-based MATLAB function bvp4c is implemented to handle the envisioned mathematical model. Sketches portraying impacts on velocity, temperature, and concentration versus involving parameters are given and deliberated well. It is witnessed that Darcy-Forchheimer coefficient show an opposite trend on radial velocity and temperature field. It is further perceived that melting parameter and radiation parameter has a retarding effect on temperature profile. Skin friction coefficients (SFC) and local Nusselt number (Nul) are evaluated via graphical illustration. Our results demonstrate that the SFC fall for porosity parameter and Nul is boosted for higher values of melting parameter and is reduced in case of high radiation coefficient.
