Title: The radial velocities of axisymmetric jets and plumes
Authors: Chen, Ying
Issue Date: 2000
Abstract: In the present experiments, the MicroADV is used in the investigation of the submerged round jet and plume in a stationary uniform ambient fluid. Although jets and plumes have been the subject of numerous studies, reliable experimental data on the radial velocities of these flows are still comparatively sparse. The radial velocity is very relevant to a thorough understanding of the turbulent jet or plume and the entrained flow that surround it. However, few studies have focused on measuring these velocities, because the mean radial velocity is very small compared to the mean axial velocity. In this paper, we will describe both theoretical and experimental investigations into the entrained flow field. The data from the present experiments show that radial velocities can be modeled effectively assuming the axial velocity profiles are Gaussian and self-similar. A comparison with earlier studies shows that the data are more consistent with the analytical curve. Axial velocities as well as radial and axial turbulence statistics are also presented and compared with previous studies.
