Flow Around Flapping Flexible Flat Plate Wings

This study investigates the unsteady flow phenomena generated from plunging wings with varying flexibility. The experiments were conducted in a wind tunnel with forward flight conditions at a chord based Reynolds number of 5300. The wings are fabricated out of homogeneous isotropic materials with values of 55 and 1702. The conditions of these experiments are matched to previous studies in a wat...

Unsteady Reversed Stagnation-Point Flow over a Flat Plate

This paper investigates the nature of the development of two-dimensional laminar flow of an incompressible fluid at the reversed stagnation-point. ”. In this study, we revisit the problem of reversed stagnation-point flow over a flat plate. Proudman and Johnson (1962) first studied the flow and obtained an asymptotic solution by neglecting the viscous terms. This is no true in neglecting the vi...

Unsteady flow field around a human hand and propulsive force in swimming.

Much effort has been undertaken for the estimation of propulsive force of swimmers in the front crawl. Estimation is typically based on steady flow theory: the so-called quasi-steady analysis. Flow fields around a swimmer, however, are extremely unsteady because the change direction of hand produces unsteady vortex motions. To evaluate the force correctly, it is necessary to know the unsteady p...
