Micro- and nanoscale phase change phenomena are important for a number of applications such as thermal management of electronic devices and spacecraft, micro- and nanoscale manufacturing, water desalination, thermoelectric and nuclear power generation, and energy harvesting. Progress in such applications requires advances in experimental techniques, mathematical modeling, and large-scale numerical simulations. Significant progress has been made in each of these areas in the respective research communities and discussed at many specialized conferences. The objectives of the present meeting are to provide a forum for exchange of ideas between these different communities and to focus on interdisciplinary approaches leading to a better fundamental understanding of the underlying processes governing heat transfer, fluid flow, and mass transfer over a range of length and time scales. Of particular interest will be applying recent advances in multiscale modeling, artificial intelligence, and metrology techniques to the study of phase change phenomena at the micro- and nanoscale.
