Shear-driven / gravity-driven thin liquid film in separated flow and turbulence modelling

Hai Lan

Abstract

"Gravity-driven and shear-driven thin liquid film flows are studied through numerical simulation and experimental measurements. The two types of film flows are often encountered in engineering applications, especially for the port-fuel-injection engine in a cold-start period. The better understanding of the dynamics of the films is helpful for reducing emission and improving efficiency. Parametric studies were conducted through 3-D numerical simulations for the two types of film flows in straight ducts. The numerical results are presented to show the effect of film mass flow rate, surface tension, gas phase velocity and gravity force on film thickness, film width and film velocity. The numerical results compare favorably with measurements"--Abstract, page iv.
