In the frame of the IFMIF-CDE, the activity summarised here has been carried out. A thermal-hydraulic design analysis, starting from the results of a Water Eexperiment of High Speed, Free Surface, Plane Jet Along Concave Wall, have been performed. Previous analyses were driven by computed nozzle outlet velocity profiles following a well-known analytic expression. As kind of experimental velocity profiles becomes available, their thermal-hydraulic consequences on the main design parameters have to be compared with their most updated amounts. The present work shows both experimental nozzle-outlet and jet-bulk velocity profiles matching design constraints slightly better than previously assumed nozzle-outlet velocity distribution function.
