  • Investigation of the use of High Pressure Water for Spun ...

    2020-4-16 · Experimental Methodology It is known that according to burnoil‟s principle, high pressure-water flow has an ability to suck air through a capillary from outside atmosphere. The principle is going to apply to increase the turbulence in water by mixing air with water inside the texturing jet. Therefore further studies were carried out using a water-jet that sucks air from atmosphere. To differentiate the …
