Swirling flow of fluid containing (SiO₂) and (MoS₂) nanoparticles analyze via Cattaneo-Christov theory

Abstract

Investigation of heat transport mechanism in swirling flow of viscous fluid containing silicon dioxide [Formula: see text] and molybdenum disulfide [Formula: see text] nanoparticles is performed. The flow is engendered due to stretchable rotating cylinder which immersed in infinite fluid. The boundary layer assumption is applied to simplify the governing equations of the problem. The theory of Cattaneo-Christov for thermal energy transportation is employed in the present phenomenon under the heat and mass constraints. The flow is also influenced by Lorentz force. The results for flow field, temperature, and concentration field are produced by employing the bvp4c numerical technique to the similar differential equations. According to the observations, it is noted that in the presence of Lorentz force the reduction in velocity field of the nanofluid occurs. The thermal and solutal relaxation phenomena also declines the energy transport in nanofluid flow. The outcomes are validated through the comparison with previous published studies.

Irreversibility process analysis for SiO2-MoS2/water-based flow over a rotating and stretching cylinder

“…The bvp4c approach is used to calculate the Nusselt number’s values. Table 4 is presented to validate the results of problem by comparing them with the previously published papers, Fang and Yao 8 and Zhang et al 13 The table is constructed by varying the values of Reynolds number and neglecting hybrid nanofluid conduct and magnetic effects for coefficients of shear stresses. It is found that f ~ ″ ( 1 ) and g ~ ′ ( 1 ) decrease by augmenting the R e The results obtained are in good agreement with Fang and Yao 8 and Zhang et al 13 as a special case, that is , for M = 0 .…”

“…Additionally, a high ductility is achieved with a high strain hardening rate by including these components in the high-strength steel grade. 13 as a special case, that is, for M = 0 .…”

“…The characteristics of flow and heat transfer analysis are studied by using the heat source-sink parameter and Ohmic heating effects. The current work is motivated by Zhang et al 13 and is an extension of their work. The governing PDEs are transformed into dimensionless ODEs by using similarity conversions.…”

“…Jusoh et al 11 presented the dual solutions of the MHD rotating ferrofluid over the stretching sheet via the bvp4c function. Incitation of flow due to extension and rotation of the disk along with magnetic and Joule heating impacts was concentrated by Ahmed et al 12 Using the heat source – sink parameter, Zhang et al 13 investigated the heat transfer characteristics of the nanofluid flow caused by stretching and torsional motion of the cylinder.…”
