Report

The International Workshop on Multiphase Flows: Analysis, Modelling and Numerics 2025, organized by the Mathematics and Physics Unit “Multiscale Analysis, Modelling and Simulation” of Waseda University, was held over three days from December 10 to 12, 2025. The workshop aimed to promote collaborative research between engineering and mathematics and brought together researchers from different fields for discussion.
A total of six researchers from Japan and abroad were invited, and fifteen presentations were given, including nine by doctoral students from Waseda University. Throughout the workshop, active question-and-answer sessions and discussions took place. In addition to facilitating interaction among researchers from different disciplines, the workshop provided doctoral students with a valuable opportunity to receive constructive feedback on their research presentations.
