Investigation on Thermally Radiative Mixed Convective Flow of Carbon Nanotubes/Al2O3 Nanofluid in Water Past a Stretching Plate with Joule Heating and Viscous Dissipation

Abstract

The nature of this prevailing inquisition is to scrutinize the repercussion of MHD mixed convective flow of CNTs/Al2O3 nanofluid in water past a heated stretchy plate with injection/suction, heat consumption and radiation. The Joule heating and viscous dissipation are included in our investigation. The Navier–Stokes equations are implemented to frame the governing flow expressions. These flow expressions are non-dimensioned by employing suitable transformations. The converted flow expressions are computed numerically by applying the MATLAB bvp4c procedure and analytically by the HAM scheme. The impacts of relevant flow factors on fluid velocity, fluid temperature, skin friction coefficient, and local Nusselt number are illustrated via graphs, tables and charts. It is unequivocally shown that the fluid speed declines when escalating the size of the magnetic field parameter; however, it is enhanced by strengthening the Richardson number. The fluid warmness shows a rising pattern when enriching the Biot number and heat consumption/generation parameter. The findings conclusively demonstrate that the surface drag force improves for a larger scale of Richardson number and is suppressed when heightening the unsteady parameter. In addition, it is evident from the outcomes that the heat transfer gradient decreases to increase the quantity of the Eckert number in the convective heating case; however, the opposite nature is obtained in the convective cooling case. Our numerical results are novel, unique and applied in microfluid devices such as micro-instruments, sleeve electrodes, nerve growth electrodes, etc.

Numerical investigation of chemically reacting jet flow of hybrid nanofluid under the significances of bio-active mixers and chemical reaction

“…Further, they have employed the concepts of the Buongiorno model for the computation of energy communication. Prabakaran et al [ 7 ] have deliberated the thermal operation of the CNT/ nanofluid in water over the stretching surface by using the applications of the homotopy analysis technique. It has been distinguished that the intensification of the Richardson number improved the surface drag force.…”

Computational Analysis of Darcy–Forchheimer Flow of Cu/Al–Al2O3 Hybrid Nanofluid in Water over a Heated Stretchable Plate with Nonlinear Radiation

“…The flow of an -based HNF with heat absorption and generation was examined by Zainal et al [ 28 ]. Prabakaran et al [ 29 ] developed a mathematical model for the flow of water-based CNTs past an SS with heat consumption/generation. They noted that the greater presence of the HAG parameter decayed the HTG.…”
