Description
Summary:A mathematical model is constructed to examine the impact of magnetic field and thermal radiation on flow and heat transfer analysis of carbon nanotubes-based nanofluids by taking base fluid as the water between two revolving stretchable disks with convective boundary conditions in the present investigation. The most extensively validated finite element technique is employed to solve the reduced nonlinear ordinary differential equations together with boundary conditions. Velocity and temperature distributions are calculated and are displayed through graphs for various values of pertinent parameters entered into the problem. Furthermore, the values of rates of change of velocity and temperature are examined in detail and are portrayed in tabular form. The values of skin friction coefficient at both upper and lower disks elevates in the boundary layer regime with rising values of Deborah number in both nanofluids, and this augmentation is higher in MWCNTs–water- than SWCNTs–water-based Maxwell nanofluid. Temperature of the fluid in both nanofluids deteriorates as the values of nanoparticle volume fraction parameter upsurge, and this deterioration in temperature distributions is higher in SWCNTs–water- than the MWCNTs–water-based Maxwell nanofluid.
