An experimental investigation was performed to study the flow structure of a submerged water jet impinging normally on a smooth and flat surface using particle image velocimetry (PIV). The jet issued from a 112 diameter long pipe which ensured fully developed turbulent flow conditions at the outlet. A semiconfined setting provided properly characterized flow boundary conditions. The Reynolds number based on jet mean exit velocity was Re = 15,895. The pipe-to-plate separation was varied between 1 and 8 pipe diameters. The current study focused on characterizing the flow structure close to the pipe outlet, in the impingement and wall-jet regions. Statistically averaged mean and RMS velocities are reported for a 6D wide and 1D high, near-plate, rectangular region. [DOI: 10.1115/1.4004907]
