Abstract

An in-house numerical solver for the unsteady, free-surface, homogeneous 3D Navier-Stokes equations has been used to investigate the response of Lake Balaton (Hungary) to synthetic wind forcing with special attention paid to the unsteady development of recirculating patterns and water transfer processes induced by the complex topography. The eddy-viscosity profiles obtained with an algebraic model and with the standard k-ε closure are also shown. The governing equations are discretised with a finite volume method and integrated in time according to a fractional-step method
