Badania struktury i charakterystyki przepływu płaskiej strugi wodnej i wodno-ściernej

STRESZCZENIE: W referacie zaprezentowano istotne aspekty badań struktury i charakterystyki przepływu płaskiej strugi wodnej i wodno-ściernej wytwarzanej w dyszy szczelinowej. Badania takie przeprowadzane w Nihon University w Japonii, metodą prześwietlania takiej strugi suspensyjnej przy użyciu techniki laserowej (PIV), pozwalają na wyodrębnienie zachowań poszczególnych jej składników w strefie erozji oraz określenie rozkładów prędkości cząstek materiału ściernego.

SŁOWA KLUCZOWE: wysokociśnieniowa struga wodna, wysokociśnieniowa struga wodno-ścierna, struktura strugi, badania PIV

ABSTRACT: The paper presents the research of the structure and characteristics of flat jet, generated in fan-jet nozzle’s type, during water-and abrasive-water jet creation. Such kind research was conducted utilizing PIV system (a YAG type laser) for isolating different structures of the jet in the erosion zone as well as for determination of their velocity fields.

KEYWORDS: high-pressure water jet, high-pressure abrasive water jet, jet structure, particle image velocimetry (PIV) examinations
