Sinopsis

The influence of decreasing the distance between artificially activated nucleation sites and a naturally activated nucleation site on their activity was studied. A naturally activated nucleation site was activated during saturated water pool boiling at atmospheric pressure using electrical or laser heating of a relatively large surface of 25 μm copper or titanium foil. The interaction between nucleation sites located at various distances was observed during their simultaneous activation with a laser heated spot, which could be moved along the surface. The results of measurements indicate that the influences of active nucleation sites on each other's activity are mutual. Moving a laser heated spot along the surface was used to show the influence of location on the activity of nucleation sites.
