The classical Smoluchowski equations, however, deal with uniform systems without any space inhomogeneities and fluxes. This is certainly too idealistic a model for real-life aggregation processes ...

How useful is Bernoulli's equation? How restrictive are the assumptions governing its use? Here we give some examples. Consider the steady, flow of a constant density fluid in a converging duct, ...

These models solve the governing equations of fluid dynamics — the Navier–Stokes equations, appropriately scaled for this application — in three dimensions, covering the globe and ...
