Diffusion of passive scalars in fluid flows: Maps in three dimensions Academic Article uri icon


  • It has been the ccntral goal of hydrodynamics for more than a ccntury to predict thc velocity field, u, of fluid flows in various gcometries. The purpose of the present work is to investigate the relations between given velocity fields and the cOITesponding trajectorics of marker particles (passive scalars) suspended in the fluid. This problem is important in the theory of mixing of fluids which in turn has a fundamental role in fields like combustion and chemical reactions. Understanding the behavior of marker partieles is also crucial in evaluating the …
