WebJan 14, 2024 · We demonstrate how many classes of Smoluchowski-type coagulation models can be realised as multiplicative Grassmannian flows and are therefore linearisable, and thus integrable in this sense. First, we prove that a general Smoluchowski-type equation with a constant frequency kernel, that encompasses a large class of such … WebA simplified form of the vorticity equation is derived for arbitrary coordinate systems. The present work unifies and extends the previous finding that while vorticity is conserved in planar Euler flow, in axisymmetric Euler rings it is the ratio of the vorticity to the distance from the symmetry axis that is conserved. The unifying

The solution of the equations is a flow velocity.It is a vector field—to every point in a fluid, at any moment in a time interval, it gives a vector whose direction and magnitude are those of the velocity of the fluid at that point in space and at that moment in time. It is usually studied in three spatial dimensions and one time dimension, although …
