Thermally developed generalized Bödewadt flow containing nanoparticles over a rotating surface with slip condition

Abstract

Recent advanced nanotechnology trends have developed thermal implications of nanoparticles as they are more and more important in different engineering and thermal extrusion technologies. Nanofluids are the best substitute to improve the thermal conductivity of conventional heat transfer base liquids. Therefore, the present article addresses the comparative study for the heat transfer phenomena in the thermal boundary layer due to a generalized VF of NF over an infinite rotating disk with generalized SC. The motion is generated by the fluid rotation like a solid body with a constant angular velocity Ω at a sufficiently extensive distance from the disk's surface. The nanoparticles Cu and TiO2 are considered with water-based NF subjected to thermal radiation. Finite difference-based method bvp4c is employed to solve the obtained non-linear ODEs numerically. The analysis of various flow parameters on the velocity components and temperature fields at the surface of the disk is outlined through graphical and tabular outcomes. The findings reveal that suction reduces the velocity overshoot and dampens the fluctuation.
