Welcome to the Fluid Dynamics Research online submission and peer review system. Fluid Dynamics Research is a well-established international journal which publishes theoretical, numerical and experimental studies that contribute to the fundamental understanding and application of fluid phenomena. It is an invaluable resource for physicists and researchers in engineering interested in problems relevant to the motion of fluids. Featuring invited reviews and original papers on topical subjects by leading researchers in the field, the journal’s coverage is broad and will appeal to researchers working in the interdisciplinary field of fluid dynamics. Fluid Dynamics Research is the official journal of the The Japan Society of Fluid Mechanics and is published by IOP Publishing on behalf of the society.
