Experimental verification of an Oseen flow slender body theory
Consider uniform flow past four slender bodies with elliptical cross-section of constant ellipticity along the length of 0, 0.125, 0.25 and 0.375, respectively, for each body. Here, ellipticity is defined as the ratio of the semiminor axis of the ellipse to the semimajor axis. The bodies have a pointed nose which gradually increases in cross-section with a radius of curvature 419mm to a mid-sec...
متن کاملComputing Flows Around Microorganisms: Slender-Body Theory and Beyond
We present the mathematical framework that governs the interaction of a forcegenerating microorganism with a surrounding viscous fluid. We review slender-body theories that have been used to study flagellar motility, along with the method of regularized Stokeslets. We investigate the role of a dinoflagellate transverse flagellum as well as the flow structures near a choanoflagellate.
متن کاملDoes Dropping out of School Mean Dropping into Delinquency?*
Approximately one third of U.S. high-school freshmen do not earn their high-school diploma on time. For African-American and Hispanic students, this figure nearly reaches one half. The long-term economic consequences of dropping out of school for both the student and the larger community have been well documented. It has also been argued that school dropouts put themselves at a higher risk for ...
متن کاملThe Properties of a Thin Conically Cambered Wing according to Slender-Body Theory
Slender-body theory is used to calculate the lift and drag forces acting on a thin slender delta wing cambered to form part of the surface of a circular cone, in the type of flow in which separation is from the trailing edge only. The boundary condition satisfied by the flow on the wing surface is applied there, instead of on a nearby plane as is usual in linearized theory. This has relatively ...
متن کاملSlender-Body Methods for Predicting Ship Squat
A review is made of linear slender-body methods for predicting the squat of a ship in shallow open water, dredged channels or canals. The results are summarized into a general formula based on Fourier transforms, and the method is extended to cater to stepped canals. An approximate solution for canals of arbitrary cross-section is proposed.
