Turbulent characteristics and air entrainment patterns in breaking surge waves

Z Li, A Venkateshwaran, S Karimpour - Fluids, 2021 - mdpi.com
Breaking surge waves are highly turbulent three-dimensional (3D) flows, which occur when
the water flow encounters a sudden change in depth or velocity. The 3D turbulent structures …

A two-dimensional inviscid model of the gravity-current head by Lagrangian block simulation
