The development of dual bluff body vortex flowmeters
WebCavitation dynamics and vortex shedding in a bluff body by Roshko ( 1955, 1993), and Saffman & Schatzman (1982) reveal the dependence of wake shedding dynamics, mainly the Strouhal number, on drag and Reynolds number. Roshko (1961 ) discusses the effect of Reynolds number regime based on experimentally WebA bluff body is an object that, due to its shape, causes separated flow over most of its surface. This is in contrast to a streamlined body, like an airfoil, which is aligned in the stream and causes less flow separation. The purpose of this study is to use hydrogen bubbles as a method of visualizing flow patterns. trout fishing in west sussex

WebA streamlined body looks like a fish, or an airfoil at small angles of attack, whereas a bluff body looks like a brick, a cylinder, or an airfoil at large angles of attack. For streamlined bodies, frictional drag is the dominant source of air resistance. For a bluff body, the dominant source of drag is pressure drag. WebBluff definition, good-naturedly direct, blunt, or frank; heartily outspoken: a big, bluff, generous man. See more. WebJun 1, 1996 · Introduction and background If a bluff, i.e. unstreamlined, body is placed in the path of a fluid, vortices are shed alternately from the top and bottom surfaces of the body. The frequency f of vortex shedding is given by: U f= St~ (1) where U is the fluid velocity at the bluff body, d is the width of the bluff body and St is a dimensionless ... trout fishing in the lake district
