Energy consistent discontinuous Galerkin methods for a quasi-incompressible diffuse two phase flow model [PDF]
, 2013 We design consistent discontinuous Galerkin finite element schemes for the approximation of a quasi-incompressible two phase flow model of Allen--Cahn/Cahn--Hilliard/Navier--Stokes--Korteweg type which allows for phase transitions.

Constraining an eddy energy dissipation rate due to relative wind stress for use in energy budget-based eddy parameterisations [PDF]
Ocean Science, 2023 A geostrophic eddy energy dissipation rate due to the interaction of the large-scale wind field and mesoscale ocean currents, or relative wind stress, is derived here for use in eddy energy budget-based eddy parameterisations.
