The waves amplitudes increase due to interacting with thermocapillary structures

Abstract

The analysis of experimental data on the simultaneous measurement of the thickness and temperature fields in the flowing heated liquid film at Re = 15 is presented. It is shown that increasing heat flux results in more expressed rivulet formation in the lower part of the heater (differential thicknesses in the rivulet and interrivulet area increases from 0.04 mm to 0.11 mm). It was found that the wave amplitude increase in the region where waves interact with the thermocapillary structures.
