Settling and swimming of flexible fluid-lubricated foils.

چکیده
We study the dynamics of a flexible foil immersed in a fluid and moving close to a rigid wall. Lubrication theory allows us to derive equations of motion for the foil and thus examine the passive settling and the active swimming of a foil. This also allows us to partly answer the long-standing question in cartoon physics--can carpets fly? Our analysis suggests a region in parameter space where one may realize this dream and move the virtual towards reality.

Undulatory locomotion of flexible foils as biomimetic models for understanding fish propulsion.
An undulatory pattern of body bending in which waves pass along the body from head to tail is a major mechanism of creating thrust in many fish species during steady locomotion. Analyses of live fish swimming have provided the foundation of our current understanding of undulatory locomotion, but our inability to experimentally manipulate key variables such as body length, flexural stiffness and...
متن کاملThe hydrodynamic function of shark skin and two biomimetic applications.
It has long been suspected that the denticles on shark skin reduce hydrodynamic drag during locomotion, and a number of man-made materials have been produced that purport to use shark-skin-like surface roughness to reduce drag during swimming. But no studies to date have tested these claims of drag reduction under dynamic and controlled conditions in which the swimming speed and hydrodynamics o...

Synopsis Considerable progress in understanding the dynamics of fish locomotion has been made through studies of live fishes and by analyzing locomotor kinematics, muscle activity, and fluid dynamics. Studies of live fishes are limited, however, in their ability to control for parameters such as length, flexural stiffness, and kinematics. Keeping one of these factors constant while altering oth...

متن کاملReview of Hydrodynamic Scaling Laws in Aquatic Locomotion and Fishlike Swimming
We consider observations and data from live fish and cetaceans, as well as data from engineered flapping foils and fishlike robots, and compare them against fluid mechanics based scaling laws. These laws have been derived on theoretical/numerical/experimental grounds to optimize the power needed for propulsion, or the energy needed for turning and fast starting. The rhythmic, oscillatory motion...
