Heat and Mass Transfer Analysis of Single Walled Carbon Nanotubes-Water and Multi Wall Carbon Nanotubes-Water Based Maxwell Nanofluid Flow Over Stretchable Rotating Disks

Abstract

Influence of thermal radiation and magnetic field on heat transfer and flow analysis of water-CNTs type nanofluid between two stretchable revolving disks with heat generation/absorption and convective boundary condition is numerically examined in this analysis. The most extensively validated Finite element technique is employed to solve the reduced non-linear 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 co-efficient 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 upsurges and this deterioration in temperature distributions is higher in MWCNTs-water than the SWCNTs-water based Maxwell nanofluid.
