In this thesis, we examine the interactions between active nucleation sites during subcooled
boiling of the dielectric fluid FC-72 at atmospheric pressure, focusing on distances between
nucleation sites (30, 60, 90, 120, and 200 μm). The emphasis is on the impact of the distance
between active nucleation sites and the formation of coalescence. An optical tweezer was
used for heating and creating nucleation sites across the heating surface. We found that the
distance influences the interactions and identified an interval estimate for the minimum
distance between two nucleation sites where two bubbles do not form.
