MHD Slip Flow of CNT-Ethylene Glycol Nanofluid due to a Stretchable Rotating Disk with Cattaneo–Christov Heat Flux Model

Abstract

This article deals with carbon nanoliquid flow due to stretchable rotating disk with the effect of Cattaneo–Christov heat flux model. Both SWCNTs and MWCNTs are considered with ethylene glycol as the base fluid. The effects of nanoparticle volume friction, normally applied magnetic field, stretching factor, velocity, and thermal slip factors are examined. The fundamental flow governing equations are transformed into dimensionless system of coupled nonlinear ordinary differential equations, and they are solved numerically using spectral quasi-linearization method (SQLM). Employing graphs and tables, the results of velocity and temperature fields as well as skin friction coefficient and local heat transfer rate are analyzed and presented via embedded parameters. The results reveal that higher velocity fields and lower temperature fields are noticed in the MWCNT nanofluids than SWCNT nanofluids. The higher incidence of magnetic field improves the thermal boundary layer thickness. A growth in velocity slip factor reduces the momentum boundary layer thickness of the nanoliquid flow. Generally, radial stretching of the disk is helpful in improving the cooling process of the rotating disk in practical applications.

Effects of Second-Order Slip Flow and Variable Viscosity on Natural Convection Flow of CNTs − Fe

“…Also, the thickness of the thermal boundary layer enhances for bigger values of R, which increases the temperature profile. As well, the same pattern of velocity and temperature distribution in hybrid nanofluids flow was observed by Tulu and Ibrahim [8] and Manjunatha et al [25]. e impacts of Grashof number (natural convection parameter) τ on velocity and temperature profiles are presented in Figures 7 and 8, respectively.…”

“…e values of thermophysical properties of nanoparticles CNTs, Fe 3 O 4 , and base fluid are given in Table 1 (Tulu and Ibrahim [8], Alsagri et al [9], Sundar et al [24], and Hayat et al [41]). e hybrid nanofluid effective thermophysical properties models are given in Table 2 (Alsagri et al [9] and Manjunatha et al [25]).…”

“…e inner and outer diameters of MWCNTs are determined by their number of layers (Khalid et al [7]). CNTs are the resourceful material of modern technologies because of their special thermal, electrical, and mechanical characteristics, unique morphology, and innovative physicochemical features, and the presence of carbon chains in CNTs does not convey any hazard to the atmosphere (Tulu and Ibrahim [8] and Alsagri et al [9]).…”

“…The MHD radiative and incompressible steady flow of Carreau nanofluid explored with carbon nanotubes are investigated by Nagalakshm & Vijaya 30 . Tulu and Ibrahim 31 scrutinized the carbon nanofluid flow with the result of Cattaneo–Christov heat flux model due to stretchable rotating disks. Both SWCNTs and MWCNTs are known as the base fluid of ethylene glycol.…”

“…Chaudhary and Kanika (2019) numerically explored a Marangoni convective MHD flow of CNTs nanofluid with radiation effects. Recently, Tulu and Ibrahim (2020) discussed a magneto-hydrodynamic slip flow of CNT-EG nanofluid over a rotating stretchable disk along Cattaneo-Christov heat flux model.…”
