Recently, Larsen and Fuhrman (2018) have shown that seemingly all commonly used (both k-ω and k-ε variants) two-equation RANS turbulence closure models are unconditionally unstable in the potential flow beneath surface waε use of a modified eddy viscosity. In the present work, three new formally-stable k–ω turbulence model formulations are derived and tested in CFD simulations involving the flow and dynamics beneath large-scale plunging breaking waves, based on experiments of van der A et al. (2017).
