Wave Radiation Stresses
The wave radiation stresses are calculated using linear wave theory as (Longuet-Higgins and Stewart 1961; Dean and Dalrymple 1984)
- f = the wave frequency [1/s]
- = the wave direction [rad]
- = wave energy = [N/m]
- = significant wave height [m]
- = wave unit vector = [-]
- = wave group velocity [m/s]
- = wave celerity [m/s]
- = wave number [rad/s]
The wave radiation stresses and their gradients are computed within the wave model and interpolated in space and time in the flow model.
