... to overcome the additional problems that are introduced by the existence of pipe-junctions. Pipe-junctions are areas in the pipeline where three pipes intersect. At those points one of two things will happen: either two incoming streams of fluid will be merged into one outgoing stream; or one incoming stream...

... Abstract Air-water two-phase flow in circular pipes has been studied by many investigators. Because of the important effect of flow patterns on the flow and heat transfer, investigations on flow patterns are still very active. On the other hand, investigations of flow patterns in noncircular...

In many ways the solutions of pipe flow equations look like the solutions of nonlinear diffusion equations, so it is natural that schemes that work well for diffusion problems might...
