a Wave energy variation with (non dimensional) time. Solid line: wave train total energy Ek + Ep[J. m−1] (black dots: fraction corresponding to the leading wave), “ × ”: wave train kinetic energy Ek[J. m−1], “ + ”: wave train potential energy Ep[J. m−1], dotted line: instantaneous dissipation rate in water ϕw[J. s−1. m−1] with the shaded area, the turbulent contribution to this dissipation rate. The colored vertical dashed lines in (a) refers to the time instant of the following panels (i.e., (b–e)). b–e Snapshots of the fluid interfaces, streamlines, and turbulent dissipation rate ϵ around the leading wave at different phases of the wave life for the same case as (a), with (b) Generation phase, (c) Transition, (d) Weak breaking and (e) Propagation phase.
