About the Cover
Cover:
A rainbow trout Oncorhynchus mykiss swimming behind a D-cylinder in flowing water. Liao, Beal, Lauder and Triantafyllou (pp. 1059-1073) describe a novel mode of locomotion for trout swimming in a vortex street, which they term the Kármán gait. By systematically altering the cylinder diameter and flow speed, the authors show that trout will change their swimming kinematics to synchronize to the hydrodynamic wake variables.
