Impinging jet inclined
WitrynaAbstract The entrainment rates of vertical and inclined jets impinging on a stratified interface are measured in water tank experiments. At moderate Richardson number, the entrain-ment rate of the vertical jet is proportional to Ri~1/2, indepen-dent of Reynolds number. The inclined jets are tilted at 15¡ from the vertical. Witryna16 gru 2024 · The oblique impingements of both single circular and planar slot jets were considered in particular. The review focused on the surface where the jet …
