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

J Appl Biomater Funct Mater. 2022 Jan-Dec:20:22808000221094685. doi: 10.1177/22808000221094685.

Abstract

Investigation of heat transport mechanism in swirling flow of viscous fluid containing silicon dioxide (SiO2) and molybdenum disulfide (MoS2) 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.
