Summary:Recently, the development of the high-performance heat exchanger is desired from the view point of saving energy and resources. The application to the heat exchanger of dropwise condensation phenomenon which shows high heat transfer performance is desired. However, the relationship between the behavior of the condensate droplet and the heat transfer on the wide condensing surface in dropwise condensation has been not clarified. In this study, the heat transfer characteristics under dropwise condensation are investigated by the calculation and the experiment when the vertical condensing surface is vibrated in gravitational direction. As a result, we found that the heat transfer coefficient was enhanced by the vibration.
