[HTML][HTML] A quantitative study on the turbulent kinetic energy redistribution in the near free-water-surface region of open channel flows

S Jing, Y Duan, D Li - AIP Advances, 2023 - pubs.aip.org
Open channel flows (OCFs) exhibit unique characteristics compared with other wall-
bounded flows due to the presence of a free water surface. One of the well-known features is …
