Radiative Darcy-Forchheimer Micropler Bödewadt flow of CNTs with viscous dissipation effect

Abstract

[EN] This article aims at the examination of the three-dimensional micropolar nanofluids of single and multi-walled carbon nanotubes (CNTs) dissolved in water and gasoline liquids for the first time reported to the case of so-called classical Bodewadt flow, which occurs when a fluid rotates at an adequate great distance out of a static disk. The static disk is then stretched linearly in the radial direction. The Darcy-Forchheimer porous media are also taken into account. Energy equation is investigated in existence of convection and radiation. The effect of viscous dissipation is also taken into account. The flow field equations are converted from PDEs to ODEs using appropriate transformation. The implementation of the bvp4c technique (Shooting scheme) is used to construct solutions to these ODEs. In addition to Nusselt number, skin friction, axial velocity, radial velocity, tangential velocity, micro-rotational velocities and fluid temperature are all investigated using physical factors. The finding indicates that the volume fraction enhanced, the micro-rotational velocities enhances. The tabulation outcomes indicates that the skin friction declined for escalating values of porosity parameter and volume fraction, while Nusselt number show opposite behavior. It has been also discovered that the effect of multiple-walled CNTs is quite effective than that of single-walled CNTs. When compared to water-based fluids, gasoline oil also displays an overarching trend.
