Description	The configuration of a submerged, circular, unconfined impinging air jet, which issues from a bell-shaped converging nozzle, is characterized numerically and experimentally. A commercial CFD package is repeatedly employed to simulate three different configurations to validate the different turbulence models, namely k–? Re-Normalized Group (RNG), k–? Shear Stress Transport (SST) and the Reynolds Stress Model (RSM). A hot-wire anemometry technique is applied to investigate extensively the flow field of the impinging jet. The comparison of results suggests that the k–? SST turbulence model is the most reliable for the flow configurations under investigation.

(en) Toková konfigurace impaktního proudění proudu tekutiny, která vychází z konvergentní trysky a dopadá na stěnu, je studována pomocí numerických simulací a ověřovacích experimentálních měření. Komerční CFD software je použit pro numerické modelování tří s cílem ověřit tři odlišné turbulentní modely: k–? RNG (“Re-Normalized Group”), k–? SST (“Shear Stress Transport”) a RSM (“Reynolds Stress Model”). Teplotní anemometrie je využita pro podrobné zmapování rychlostního pole uvnitř tekutinového proudu.Z porovnání numerických a experimentálních výsledků vyplývá, že SST model je pro danou tokovou konfiguraci nejvhodnější.
