Witryna17 wrz 2024 · An experimental and numerical investigation is conducted to study the influence of different cooling schemes on the wall temperature of the flame tube in a small triple-swirler combustor in this paper. Two different cooling structures are adopted: the impingement-film and inclined multi-hole cooling structure (Scheme B, C), and … 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.

Inclined Jet - an overview ScienceDirect Topics

WitrynaA jet, inclined in traverse direction, improves hydrodemolition processes. The gain in efficiency is up to 8% at an angle of 30° which would be the optimum angle. If, however, the jet is directed against the traverse direction, efficiency drops. This drop (down to 25%) is much more intense than the gain in efficiency. WitrynaImpinging jets are widely used in many industrial and engineering applications spanning from hydraulics and aeronautics to electronics. The interplay of pressure and velocity can be used for flow diagnostics. A Prandtl or pitot-static probe is composed of two concentric tubes. ... Jet Impinging on an Inclined Plate.
