Multiphase flow remains one of the unsolved problems in fluid mechanics. There are many factors which make it difficult to deal with such flows. They are very diverse in nature, and as a consequence the laws governing them are similarly varied. This volume contains papers presented at the fourth International Conference on Computational Methods in Multiphase Flow. Complementing the interesting mathematical and numerical problems that multiphase flows pose is an equally interesting array of real-life problems which are characterized by multiphase flow: groundwater transport, river and sea-bed sedimentation, boiling and condensation, sprays and aerosols, combustion processes in power generation equipment, and many others.
