Contrary to single-phaseflows, where the underlying physics is quite well understood and relatively generalnumerical methods can be employed in flow simulations, the physical phenomenaoccurring in two-phase flows are far more versatile and still not fundamentally un-derstood in all details. The difficulties in multiphase flow modeling arise from largedissimilarities between different types of flow configurations and the complex flowconditions associated.
