The peculiarities of nanocapillary flows are studied in the framework Newtonian and micropolar fluid models. classical problem a steady flow driven by constant pressure gradient is formulated for cylindrical with radius much smaller than its length. All possible boundary conditions (slip, no-slip, stick-slip) exploited model fluid, two alternative value problems (hyper-stick no-slip nonzero spi...

Two-dimensional Euler equations have been solved on an unstructured grid. An upwind finite volume scheme, based on Roes flux difference splitting method, is used to discretize the equations. Using advancing front method, an initial Delaunay triangulation has been made. The adaptation procedure involves mesh enrichment coarsening in regions of flow with high low gradients of flow properties, acc...

Unsteady water flows are common in nature, yet the swimming performance of fishes is typically evaluated at constant, steady speeds in the laboratory. We examined how cyclic changes in water flow velocity affect the swimming performance and energetics of a labriform swimmer, the shiner surfperch, Cymatogaster aggregata, during station holding. Using intermittent-flow respirometry, we measured c...
