Computational approaches from atomistic to environmental scale discussed State-of-the-art in computational multiphase flow methods as described by many of the world's top practitioners Lattice Boltzmann and molecular dynamics simulations for multiphase flows Wide range of applications

Zusammenfassung

The book provides a broad overview of the full spectrum of state-of-the-art computational activities in multiphase flow as presented by top practitioners in the field. It starts with well-established approaches and builds up to newer methods. These methods are illustrated with applications to a broad spectrum of problems involving particle dispersion and deposition, turbulence modulation, environmental flows, fluidized beds, bubbly flows, and many others.
