Deflection and Reattachment of a Radial Jet : (1st Report, Mean and Fluctuating Velocity Properties of Deflected Jet)

Abstract

This paper presents an experimental investigation of a radial turbulent jet (main jet) discharged from a cylindrical nozzle in the presence of a lateral control flow from an annular nozzle. The main content of this report concerns with the mean and fluctuating velocity properties of a deflected jet. The effects of the impingement conditions which are the nozzle distances in this report were claified. The measurement of mean velocities, turbulent intensities of each component, and Reynolds shear stresses were carried out. The properties of the deflected jet are affected by the control flow in the region just behind the impingement of two jets, but they agree well with those of the radial free jet in the downstream section when the components are dissolved into the mean stream direction and its perpendicular directions.
