Abstract: This paper presents analytical and numerical results for a class of turbulence closure models called ?alpha models,? in which Lagrangian averaging and turbulence closure assumptions modify the Eulerian nonlinearity. The ...

Abstract: The class of alpha models for turbulence may be derived by applying Lagrangian averaging to the exact fluid equations and then making a closure approximation based on Taylor?s hypothesis of frozen-in fluctuations. This ...

Abstract: The f-plane linear shallow-water equations support coastal Kelvin waves. These waves propagate along the coast and have zero velocity normal to the coast. It is shown that the balance equations also support coastal Kelvin ...
