We invite you to contribute to this international multidisciplinary event covering diverse areas of CFD unified by the crucial role of coupled phenomena, physical fields, and effects, as well as by multiple-scale interactions at the local and/or entire system levels. The models featured here will include a comprehensive range of areas from the recent progress in better understanding many physical, engineering, biological, and social systems. The symposium welcomes theoretical, computational, and experimental advances in this pivotal field. Further details are at http://ammcs.wlu.ca/2023/special-sessions/ccsms/
