Summary

Results for a heated metal foil on a Pyrex glass substrate show that the local heat flux at the triple point could be as much as one to two orders of magnitude higher than the input heat flux. Consequently, the wall temperature at the triple point drops rapidly, resulting in a non-uniform wall surface temperature. Both the accommodation coefficient of evaporation and lateral heat conduction in the heated wall significantly affects the liquid microlayer evaporation on a thin, highly conductive wall, especially during the early stage of the bubble growth.
