Abstract
The
numerical study found the effect of changes in the longitudinal and transverse
dimensions of the heater with keeping constant the area of heating on
evaporation intensity, dynamics, and extreme thicknesses of a thin liquid film
moving in a microchannel under the influence of the gas flow at local heating.
It is shown that for relatively small heating, evaporation is more intense for
the wide heaters than for the narrow ones. For the narrow and long heaters,
evaporation process is slower, but then it is intensified in a short time.
