Abstract

A two-dimensional water jet of 2.8mm × 280mm is discharged horizontally near thesurface of a quiescent water vessel of 1m in width, 1m in depth and 4m in length. The vertical distribution of the velocity is measured at distances of 0.5m, 1.0m and 1.5m from the discharge port. The measured valuesare compared to Reichardt theoretical result of a two-dimensional turbulent free jet and the numerical results of relevant Navier-Stokes equation with respect to the pattern of the velocity distribution, maximum velocity and half width of the jet plume. It is concluded that the principal characteristics of the present measured results agree with Reichardt's theoretical result. However, the virtual kinematic viscosity seems to be about 1/4to 1/8 of that of the air jet proposed by Reichardt.
