Abstract
Plane submerged turbulent water jet discharged parallel to the offset bottom wall in the channel with a finite water depth was investigated experimentally. Depending on the depth of the nozzle and its height from the bottom, the jet deflects towards either of the two boundaries, that is, the free surface or the solid wall. Detailed data on the velocity field measured by using the PIV method are given in order to examine the influence of the opposing boundary upon the deflecting jet and the difference of the jet development between the deflection to the free boundary and that to the solid boundary. The mean velocity profiles and the spread rates of the jet are compared with those of a conventional plane free jet applying a curved coordinate system along the jet centerline.
