Description
Multiphase flows, which can involve compressible or incompressible linear or nonlinear fluids, are found in all areas of technology, at all length scales and flow regimes. In spite of their ubiquitousness, however multiphase flows continue to be one of the most challenging areas of computational mechanics and experimental methods, with numerous problems remaining unsolved to date. Multiphase flow problems are so complex that advanced computational and experimental methods are often required to solve the equations that describe them. The many challenges include modelling nonlinear fluids, modelling and tracking interfaces, dealing with multiple length scales, characterising phase structures, and treating drop breakup and coalescence. Models must be validated, which requires the use of expensive and difficult experimental techniques. This book presents contributions on the latest research in these techniques, presented at the sixth in a biennial series of conferences on the subject that began in 2001. Featured topics include: Multiphase Flow Simulation; Turbulent Flow; Bubble and Drop Dynamics; Heat Transfer; Incline Flows; Energy Applications; Flow in Porous Media.
