Comment on 'Wakes of three axisymmetric bodies at zero angle of attack'

Abstract

the 70% porous glass fiber screen performed best. The roughness of the screen affected the velocity field but had little effect on the temperature field because of the turbulent boundary layer. More details are provided in the references.' The screen was removed when velocity measurements were made with a hot-wire anemometer. We have been investigating the heated-wire technique. The difficulty is that the flowfield of interest involves mixed convection with buoyant flow near the jet edges. However, the technique is of great interest. We appreciate the experience and recommendations of Gartenberg and Roberts.
