Investigation on Pulsating Liquid Jet with Physiological Saline on Aluminium Surface

Popis výsledku v původním jazyce

The paper deals with an experimental study related to the influence of technological parameter namely standoff distance and fluid pressure over disintegration depth created on aluminium surface. The fluid used for disintegration is 0.9% physiological saline. This saline solution with density 1.008 kg/m3 higher than water 0.998 kg/m3, when impacts the surface induces a larger force leading to deeper disintegration grooves keeping other parameters constant. Special nozzle having diameter of 0.3 mm and 100 mm length was used during disintegration process. A minimal pressure ranging from 8 MPa to 16 MPa along with standoff distance of 1 mm to 6 mm is varied to observe its interactional effect over the depth formed during disintegration process. Groove depth was measured using FRT device in which 10 readings of each groove were recorded and their mean were considered for further analysis. The results concluded that for intermediate values of standoff distance (3–4 mm) and higher fluid pressure (13–16 MPa), deeper grooves were observed. Deepest mean groove observed within the experimental domain was of 183 µm deep at 2 mm standoff distance and 16 MPa fluid pressure. The experiments concluded that saline jet can be used for disintegration of material effectively.
