The entrainment data were extracted from LDV measurements of longitudinal mean jet velocities obtained under different ambient current conditions. Two entrainment models were examined. The first model applied the entrainment coefficient α , as defined by Morton, Taylor and Turner (1956) and the second model applied the entrainment coefficient β , as defined by Townsend (1956). The results have indicated that α decreased with distance along the jet, while β was constant. 000004802 540__ $$aText je chráněný podle autorského zákona č. 121/2000 Sb. 000004802 653__ $$aSurface jet, LDV measurements, Entrainment coefficient 000004802 7112_ $$a15th ASCE Engineering Mechanics Division Conference$$cNew York (US)$$d2002-06-02 / 2002-06-05$$gEM2002 000004802 720__ $$aBaddour, R.
