Internal Flows in Marine Organisms

Abstract

In contrast to the fluid mechanics of flows ‘external’ to the aquatic animal body, our knowledge of the ‘internal’ flows is rather limited. Aquatic organisms are filled with various pipes and channels through which fluids flow. Biological systems of internal flow are both diverse and complex, partly due to the non-Newtonian character of fluids themselves, partly due to the complicated network of the internal pipes and channels, and basically due to the unknown roughness of pipe walls.
