“…Numerical simulations of breaking waves post impact of the impinging jet are a challenge to numerical schemes and consequently rare in the literature ͑i.e., Monaghan et al, 34 Chen et al, 35 and Iafrati and Campana 36 ͒. Monaghan et al 34 used the smoothed particle hydrodynamics method to simulate splash up ͑i.e., the post-breaking phase͒, Chen et al 35 solved the Navier-Stokes equations and used volume of fluid method to resolve the two-phase flow.…”

This numerical study explores the physical processes involved in breaking waves. The two-dimensional, incompressible, unsteady Navier-Stokes equations are solved in sufficiently refined grids to capture viscous and capillary effects. The immiscible interface, characterized by a jump in density and viscosity, is embedded in the domain and a hybrid front tracking/capturing method is used to characterize the moving interface of this multiphase flow. A parametric study is conducted to assess the role of surface tension, Reynolds number, density, and viscosity on the breaking process, as well as their role in the vorticity redistribution and energy dissipation beneath the surface.

“…There is little numerical simulation of this problem going beyond the time of impact of the plunging jet. In Monaghan et al, 10 the smoothed particle hydrodynamics method (SPH) was used to simulate a splash-up. However the spatial resolution of the method seems insufficient to resolve the small scale viscous and capillary effects.…”

Two-dimensional Navier–Stokes simulation of breaking waves

et al. 1999

International audienceNumerical simulations describing plunging breakers including the splash-up phenomenon are presented. The motion is governed by the classical, incompressible, two-dimensional Navier–Stokes equation. The numerical modeling of this two-phase flow is based on a piecewise linear version of the volume of fluid method. Capillary effects are taken into account such as a nonisotropic stress tensor concentrated near the interface. Results concerning the time evolution of liquid–gas interface and velocity field are given for short waves, showing how an initial steep wave undergoes breaking and successive splash-up cycles. Breaking processes including overturning, splash-up and gas entrainment, and breaking induced vortex-like motion beneath the surface and energy dissipation, are presented and discussed. It is found that strong vorticities are generated during the breaking process, and that more than 80% of the total pre-breaking wave energy is dissipated within three wave periods. The numerical results are compared with some laboratory measurements, and a favorable agreement is found

“…No data have been published to our knowledge corroborating the 1981 study by Karsten and Cita indicating a major tsunami in approximately this period, on the basis of sea-bed anomalies, although at the London conference Marinos informed us that such evidence had been identified in 1996 on the coasts of Asia Minor, where tsunami deposits were overlaid by tephra. Indeed, recent tsunami research seems more concerned with elaborate simulation models than with actual field observations (Monaghan et al 1994). The evidence of Theran pumice distribution is also better left aside as its taphonomy is debatable.…”

The eruption of the Santorini volcano and its effects on Minoan Crete

Sometime in the course of the second millennium BC, an earthquake appears to have triggered a massive eruption of the Santorini volcano. The immediate consequences of the earthquake closely followed by the eruption for Cretan society during the Late Minoan I period are rather difficult to characterize, although physical evidence in the form of Theran ash has shown up at an increasing number of sites. Certain features of the archaeological record, taken in isolation, have hardly been noticed in the past. The long-term effects of the eruption, however, have recently become more comprehensible thanks to a reconsideration of old and new archaeological evidence. The combined picture gives the impression of a period of societal stress following these events. Changes in architecture, storage and food production, artisan output, the distribution of prestige items, administrative patterns and ritual manifestations can be pinpointed archaeologically. These may and should be interpreted as disturbances in the political, economic, cult and security-related domains. It is argued that the inability of the Minoan palatial centres to adapt to changing circumstances caused by a double disaster, an earthquake followed by the eruption of Santorini, led to an increase in crisis-related situations, culminating in the widespread fire destructions which brought this palatial phase of Minoan civilization to an end and opened the way for mainland Mycenaean domination of the Aegean.
