Abstract
Heat transfer in a heated film of distilled water under the action of external artificial perturbations with “the most dangerous wavelength” and variation in the Reynolds number from 300 to 500 has been studied. It has been shown that the action of artificial perturbations with an increase in the heat flux density leads to a change in the rivulet-wave structure of the flow, increase in wave amplitudes, and, finally, heat transfer enhancement.
