Nucleate Pool Boiling on A Plain Surface

Abstract

Nucleate pool boiling of distilled water on a plain copper surface has been investigated experimentally and modeled numerically. In the experimental study, bubble behavior on a single nucleation site was observed using high-speed photography and long-distance microscopy. Diameter for a single bubble growth was determined during the ebullition cycle via recordings. Numerical simulations have been carried out using CLSVOF method using ANSYS 18.2. To verify the simulation, the bubble growth period is compared with the results of the experimental study. Data from the numerical results compare reasonably well with the experimental study.
