Verwendete Materialien und Software dimensionless entrainment is a universal function of the local Richardson number. It is found that some experiments do not conform to this hypothesis, most likely because of the vigorous initial mixing of the cloud. An empirical mixing law is proposed for this early stage which does not violate energy conservation.作者: 混沌 時(shí)間: 2025-3-25 05:18
