Abstract:
From in situ measurements of vertical velocity profiles in the marine upper layer, the eddy viscosity turbulent coefficient is estimated in reference to the unsteady Ekman model solution by using optimal control techniques based on Simultaneous Perturbation Stochastic Approximation Method.
Keywords:
turbulent marine flows, eddy viscosity, Ekman layer, optimal control
