Whither Turbulence? Turbulence at the Crossroads

In this book six topics from the theory of turbulence are discussed by outstanding experts. They analyse the value and future developments of turbulence theories. For each topic a survey is given, followed by three commentaries and a panel discussion.

Opening remarks.- Achilles and the tortoise (and the Hare) discuss CFD and turbulent flow.- The utility and drawbacks of traditional approaches.- The utility and drawbacks of traditional approaches Comment 1.- The utility and drawbacks of traditional approaches Comment 2.- The utility and drawbacks of traditional approaches Comment 3.- Discussion of "utility and drawbacks of traditional approaches".- Future directions in turbulence research and the role of organized motion.- Whither coherent structures? Comment 1.- The role of coherent structures - Comment no. 2.- The role of coherent structures Comment 3.- Discussion of "The Role of Coherent Structures".- Can dynamical systems approach turbulence?.- Fixed points of turbulent dynamical systems and suppression of nonlinearity Comment 1.- Chaotic fluid dynamics and turbulent flow Comment 2.- The utility of dynamical systems approaches Comment 3.- Discussion on the utility of dynamical systems approach.- On Moffatt's paradox or can empirical projections approach turbulence?.- The potential and limitations of direct and large eddy simulations.- On large eddy simulation using subgrid turbulence models Comment 1.- The potential and limitations of direct and large-eddy simulations Comment 2.- The potential and limitations of direct and large-eddy simulations Comment 3.- Discussion of "the potential and limitations of direct and large Eddy simulations.- What can we hope for from cellular automata?.- Prospects for a lattice gas computer.- Cellular automata and massively parallel physics Comment 2.- A new strategy for hydrodynamics - lattice gases Comment 3.- Discussion of "What can we hope for from cellular automata".- Phenomenological modelling : Present .... and future?.- Phenomenological modeling: Presentand future Comment 1.- Turbulence modeling: Present and future Comment 2.- Simplex discussion regarding "modeling: Present and future" with emphasis upon high speeds Comment 3.- Discussion on "phenomenological modeling: Present and future".
