Simulation of spray droplet dynamics over waves
conference paper
The SeaCluse model is developed jointly by ECN and FEL-TNO to study the vertical dispersion of the spray droplets generated by breaking waves, during their simultaneous partial evaporation and diffusion by turbulence in an homogeneous atmospheric surface layer. This model shares the core structure of the CLUSE code constructed by Rouault et al. (1991) to simulate the behaviour of water droplets generated at the air-water interface of a wind-wave tunnel (Mestayer et al., 1990). The original CLUSE model was used by Mestayer et al. (1990) and Rouault and Larsen (1990) to demonstrate the negative feed-back effect in the droplet evaporation over a flat water surface: the vapour released by the droplets in the air increases the humidity in the lowest air layers, which in turn reduces the turbulent surface flux of vapour. This demonstration well illustrated the breakdown of the constant flux assumption for water vapour and sensible heat in the marine atmospheric surface layer in the presence of evaporating spray droplets.
