Prediction of gradient‐based similarity functions from the Mellor–Yamada model

Gradient‐based implicit similarity functions are derived theoretically from a few variants of the Mellor–Yamada algebraic turbulence‐closure model under assumptions of local equilibrium conditions in a stably stratified shear flow. The solutions are compared with empirical functions presented by Sor...
