The fluid flow characteristics, including film thickness, shear stress, and thermal performance, are observed and analyzed. Fluid film on the circular surface is typical in many engineering applications, but the study of nanofluid film on non-circular surface is deficient in literature. The study provides a numerical model of a multi-faceted cylinder to simulate the nanofluid film on the non-circular surfaces using a volume of fluid (VOF) method. The ratio of Brownian motion to thermophoretic diffusion, NBT developed along the film thickness in phases, in which the dominant phase, the steady-state NBT phase, can be used as the average NBT. Although, in general, the heat transfer performance of Alumina and Titania is better than water, producing higher HTC and Nu on both cylinders, Water, however, displays significant improvement relative to the base thermal performance of water fluid film on the circular cylinder. � 2022, Global Digital Central.
