摘要：

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.
