Q2. What is the advanced model used to simulate nonlinear wave transformations in coastal areas?
The most advanced models, which are generally used to simulate non-linear wave transformations in coastal areas, are based either on the Nonlinear Shallow Water equations (NSW), the Boussinesq-type equations (BT), or some form of hybrid model.
Q3. What is the importance of the void fraction and interfacial velocity data?
Instantaneous void fraction and interfacial velocity data are critically needed to calibrate and improve numerical models of the two-phase flow generated beneath plunging and spilling breaking waves.
Q4. How did they find the celerity of the bubble cloud?
They identified and tracked successive bubble clouds, detailed the void fractions at each step of the breaking events, and found that, beneath the spilling breaker, the celerity of the bubble cloud compared with the phase speed.
Q5. What is the definition of a surface wave breaking?
Surface wave breaking, occurring in the open ocean or the coastal zone, is a complex and challenging two-phase flow phenomenon which plays an important role in numerous processes, including air–sea transfer of gas, momentum and energy, and in a number of technical applications such as acoustic underwater communications and optical properties of the water column.
Q6. How many void fractions were observed in a wave?
High values of void fractions (up to 100 %) were found next to the free-surface, and void fractions of at least 20% were observed for up to half a wave period after the breaking occurrence.
Q7. What is the advection-diffusion equation for interfacial ?
In the upper free-surface region above, the void fraction increases monotonically with increasing distance from the bed from a local minimum up to unity, following an analytical solution of the advection-diffusion equation for interfacial aeration/de-aeration: x Zz D xV 2 1erf1 2 1=C 50 t 1 (2)where
Q8. What type of breaker was used to measure the void fraction above and below the still water?
The temporal variation of void fraction, above and below the still water level, was analysed using three breaker types (spilling, spilling/plunging and plunging).
Q9. How do you parameterise the effects of the wave breaking?
The wave-breaking effects have to be parameterised by incorporating additional terms in the mass and momentum equations (e.g. Musumeci et al.
