Szukana fraza: [Abstract = "Most optimal solution has six small holes around the nozzle hole and a small rim covering all holes. In this case, pressure decreases only 3% in the axial direction and 4% in the radial direction at the distance of 2 mm from the front surface of the nozzle. Distribution of air velocity is still significant but its magnitude is about 35% \? 45% less than at the standard nozzle cup."]
