Determining the micro film of hexyl alcohol in laminar condition on a rotating drum

Abstract

In this research, the free surface of micro film of hexyl alcohol on a partially submerged rotating drum has been predicted using CFD (computational fluid dynamics) and compared with experimental data and analytical solution. The trend of has been found very comparable with experimental and analytical solution. A Matlab code was used to model the flow and film dynamics. Computationally it was an unsteady state problem and semi-steady state was achieved. No surfactant was present on the surface. The speed of the moving rotating drum was set a rpm. With the increase of rotating drum, the minimum film thickness increases with rpm (for {\textstyle \alpha _{o}} = 47 {\displaystyle ^{0}} and for {\textstyle \alpha _{o}} = 58 {\displaystyle ^{0}} ).
