Breaking sea waves produce air bubbles that cluster up as foam. We suggest that foam is due to the inhibition of bubble coalescence (by surfactants and other impurities). We present a novel volume-of-fluid method that can distinguish between bubble clustering and coalescence and demonstrate this effect on simulations of breaking waves.
