摘要：
Near field circular jet is studied experimentally at discharge Reynolds number range of 21000 to 100000. The effect of Reynolds number on the initial boundary layer mean velocity profile is negligible, but is significant on the exit turbulent velocity profile, extend of the partial self-reservation zone, spread of the shear layer and the viscous shear stress. With decrease Reynolds number the entrainment rate decreased.
