The Coanda Effect with Jet Displacement over Planar, Concave, and Convex Walls
Abstract
Bourque and Newman presented an extensive paper analyzing the separate effects of deflection angle and offset distance on the reattachment of flow issuing from a two-dimensional incompressible turbulent jet to an adjacent inclined flat plate. Levin and Manion combined the effects of offset distance and vertical wall incidence and derived a set of parametric equations to solve for the attachment distance at a given offset distance and deflection angle. Subsequently Perry extended the control volume model to account for inaccuracies in defining a base pressure. As part of a general investigation of the Coanda effect, the work of Levin and Manion has been expanded herein to encompass concave and convex surfaces of arbitrary planform. Two methods are outlined for determining the attachment distance for these additional planforms.
