The topic of multiphase flow is broad, encompassing a variety of fluids, transported solids and flow regimes. Research in multiphase flows is driven by the challenge of understanding such complex phenomena, as well as by practical considerations dictated by technological needs. Despite recent advances in experimental and computational capabilities, multiphase flows still present many open questions.
Originally presented at the Third International Conference on Computational Methods in Multiphase Flow, the papers included are divided into the following topic areas: Basic Science DNS and Other Simulation Tools Measurement and Experiments and Applications.
