A numerical simulation of a single bubble growth and departure in a nucleate boiling has been made and compared with corresponding experimental results. In the experiment the heated surface was made of a stainless foil and heated by a copper rod (4mm in diameter) welded on its backside. By using the narrow circular heated area the whole heat transfer region was included in the computational domain. A level set method was used to deal with the free-boundary problem, and a microlayer model was included in order to take into account the rapid evaporation at the solid-liquid contact line. The bubble growth and bubble departure were calculated repeatedly with a frequency given by experimental data. The calculated heat transfer rate and bubble departure size agree well with the experimental results.
