Analysis of a Two-Dimensional, Turbulent Wall Jet Along a Circular Cylinder (Velocity and Pressure Distributions)

概要

A two- or three-dimensional turbulent jet induced by the Coanda effect along a curved wall has been investigated by many researchers. In spite of the many studies of this Coanda-induced jet flow, the flow characteristics have not been completely understood. This paper presents a theoretical analysis using an integral momentum equation and an experimental analysis on velocity and pressure distributions for a two-dimensional jet along a circular cylinder. From the theoretical analysis, the equation of velocity distribution, pressure distribution, decay of jet centerline velocity, changes of jet width and half width, for example, are made clear, and it is shown that they are in good agreement with experimental results.
