Constructal Theory, Adaptive Motion, and Their Theoretical Application to Low-Speed Turbine Design

Adaptive fin motion has long been the evolutionary means by which birds, fish, and various water-dwelling mammals create a propulsive thrust to propel them either through air or water. During the past decade, this particular phenomenon of kinematic motion has been studied by various scholars to gain an understanding of how and why the large relative efficiencies and body accelerations are attained. Invariably, the studies are interested in gaining an understanding of the phenomena so that these motions and kinematics can be applied to engineering design efforts. Various groups have built propulsive devices that are intended to mimic motions of these highly efficient adaptive motion propulsors with various degrees of successes. This paper summarizes some of these findings, bridging constructal theory and adaptive motions, with emphasis on their application. It also presents results of a research effort made by the writers to incorporate these concepts into low Reynolds number flexible turbine design.
