Description
| - Anemometrická data získaná vyšetřováním dvou syntetizovaných proudů vytékajících z trysky o průměru 4 mm, lišících se frekvencí (25 Hz a 50 Hz) byla aplikována na řešení zatopeného proudu s jednorovnicovým modelem turbulence. Umožnilo to získat prostorová rozložení nestacionárních pohybů. Klasický přístup založený na podobnosti profilů veličin musel být modifikován a řešení přichází s novým konceptem quasi-similarity. Významným poznatkem je nalezení diskontinuity ve struktuře nestacionárních pohybů – počáteční úsek s velkými víry je vystřídán úsekem se zpočátku drobnými turbolentními pohyby. (cs)
- Anemometric data obtained on two synthetic jets issuing from 4 mm dia nozzle, differing in their frequency (25 Hz and 50 Hz), were applied to one-equation turbulence model solution of jets. It made possible evaluating spatial distributions of unsteady motion in the jets. The classical concept of similarity, however, ceased to be applicable and a concept of quasi-similarity was introduced. An important finding was the discontinuity found in the structure of the unsteady motions – the intial region dominated by large vortices is changed into a region of initially smaller/scale turbulent eddies.
