The flow of gravity-driven rivulets in the entrance region
MARIAN TRELA, IRENEUSZ KORNECKI

Abstract

The formation and development of flow of gravity-driven liquid rivulets down a vertical wall is analysed in the paper. The shape of the rivulets changes due to the interaction of gravitational, viscous and surface tension forces. A simple model based on the momentum balance is put forward showing reasonable agreement with available experimental data.

Keywords:

gravity-driven liquid, tension forces, entrance region, evaporators
