'Turbulence in Porous Media' introduces the reader to the characterisation of turbulent flow, heat and mass transfer in permeable media, including analytical data and a review of available experimental data. Such transport processes occurring a relatively high velocity in permeable media, are present in a number of engineering and natural flows. De Lemos has managed to compile, detail, compare and evaluate available methodologies for modelling simulating purposes, providing an essential tour for engineering students working within the field.- The hotly debated topic of heterogeneity and flow turbulence has never before been addressed in book format. - Offers an experimental approach to turbulence in porous media as it discusses disciplines that have been traditionally developed apart from each other.The hotly debated topic of heterogeneity and flow turbulence has never before been addressed in book format.Offers an experimental approach to turbulence in porous media as it discusses disciplines that have been traditionally developed apart from each other.
