Rotating Flow in a Nanofluid with CNT Nanoparticles over a Stretching/Shrinking Surface

Abstract

The steady three-dimensional rotating flow past a stretching/shrinking surface in water and kerosene-based nanofluids containing single and multi-walled carbon nanotubes (CNTs) is investigated. The governing equations are converted to similarity equations, and then numerically solved using MATLAB software. The impacts of rotational, suction, and nanoparticle volume fraction on the flow and the thermal fields, as well as velocity and temperature gradients at the surface, are represented graphically and are analyzed. Further, the friction factor and the heat transfer rate for different parameters are presented in tables. It is found that the heat transfer rate increases with increasing nanoparticle volume fraction as well as suction parameter in water and kerosene-based nanofluids of single and multi-walled CNTs. However, the increment in the rotating flow parameter decreases the rate of heat transfer. Multi-walled carbon nanotubes and kerosene-based nanofluid contribute to heat transfer rates better than single-walled carbon nanotubes and water-based nanofluid, respectively. A unique solution exists for the stretching surface, while two solutions are obtained for the shrinking surface. Further analysis of their stabilities shows that only one of them is stable over time.

Preface to the Special Issue on “Modelling and Simulation in Engineering”

“…The paper by N.A. Yacob et al [9] studies rotating flow in nanofluids over a permeable stretching/shrinking surface. The authors present the numerical results obtained with MATLAB software, starting from a mathematical model with carbon nanotubes (single and multi-walled), and analyse the heat and mass transfer characteristics, and also the stability of the considered solutions.…”

“…Takhar et al 16 further studied the effects of MHD flow. Yacob et al 17 reported on the steady rotating flow of fluids over an extendable or shrinkable surface. Rana et al18 performed finite element simulations to study the unsteady MHD flow with rotational effects.…”

“…The results also show that thermal radiation and the unsteadiness parameter stimulate the temperature. Nor A. Yacoub [29] numerically investigated 3D rotating flow in water and kerosene-based nanofluids with single and multi-walled CNT nanoparticles over a shrinking/stretching surface. The results show that heat transfer is enhanced when the nanoparticle volume fraction or suction parameter increases, whereas it is reduced with increments in the rotating flow parameter.…”
