Dynamic Behaviors of Condensing Clusters Based on Rayleigh Scattering Experiment

Abstract Condensation is a common physical process which widely exists in natural phenomena and thermal energy systems. In a condensation process, cluster is considered as the important bridge between vapor body and condensates. However, limited by the minimum imaging dimension of traditional measur...
