Abstract:
A water veil device for jetting out liquid as a thin film in a shape by changing the cross-section of a flow path as linear or smoothly decreasing curves and by controlling an outlet velocity u0 that is an initial value of liquid velocity u according to equation (1) in which supply pressure p of liquid is varied by a numerically controlled device 2&it;Trc+2&it;T&it;â€ƒ&it;cos&it;â€ƒ&it;Ï†x-p+g&it;â€ƒ&it;Ï &it;â€ƒ&it;t&it;â€ƒ&it;sin&it;â€ƒ&it;Ï†-u2&it;Ï &it;â€ƒ&it;trc=0(1)wherein &phgr; is an inclination angle of the water veil surface to the vertical axis, T is the surface tension of the liquid, t is the thickness of the water veil at an arbitrary point, rc is the radius of curvature, and g is gravitational force.
