Abstract content <br> &nbsp; (Max 300 words)

We discuss the origins of Mixing Length Theory (MLT) in the work of Boussinesq on eddy viscosity, and of Prandtl who implemented Boussinesq's suggestions by exploiting an analogy with transport mechanisms in the kinetic theory of gases. This enables us to identify MLT as a closure model for the Reynolds-averaged Navier-Stokes equations. We discuss the shortcomings of this method of closure and propose alternatives which may useful in astrophysical modelling.
