PATENTED JUN 1 l9?! FIG. '3
STREAMING This invention relates to gas nozzles.
Objects of the invention are to enhance the directly useable (e.g., for liquid atomization) energy in gas streams, with small nozzles that can be simply and efficiently incorporated into a wide variety of physical processes.
The invention features a fluid nozzle with an axial flow passage, an inlet of area less than that of the passage directly downstream thereof, and an even plurality of radial orifices into the passage arranged in coaxial pairs 180 apart. In preferred embodiments the inlet is a circular hole in a thin plate; the passage is a counterbore to the inlet; circular holes into the passage surround the inlet, each being'included in a pair of such holes spaced 180 apart at opposite sides of the inlet; four radial orifices spaced 90 apart are tangent to a countersink at the outletend of the passage, the area of the inlet differing from the total area of the radial orifices by no more than half the area of any one of the radial orifices; and the nozzle has a flange at its outlet end adapting it for mounting in a tube to define an annular passage surrounding the tube and communicating with the radial orifices, the tube having an inlet opening of diameter approximately equal to that of the nozzle at its inlet end.
Other objects, features, and advantages of the invention will be apparent from the following description of a preferred embodiment thereof, taken together with the drawings thereof, in which:
. FIGS. 1 and 2 are perspective views, from different vantage points; and
FIG. 3 is a vertical sectional view showing the nozzle of FIGS. 1 and 2 mounted, as preferred, in a cell.
Nozzle has a cylindrical wall 12 (outside diameter 0.346 inch, inside diameter 0.260 inch) open at its outlet end across 45 countersink 14, which is surrounded by annular flange 16.
Axial inlet 18 (diameter 0.177 inch) in end wall 19 is concen- Additional dimensions of the assembly are: I h
nc Length of tube 30 between downstream face of wall 38 and upstream face of counterbore 32 0. 267 Length of nozzle 10 between wall 19 and countersink 14 0. 221 Depth of countersink 14 0. 029
, In operation, air at greater than atmospheric pressure (e.g., at between /4 and 20 p.s.i.g.) is supplied to inlet 36 and flows through nozzle inlet 18, and holes 20 and 22, and out of the nozzle across countersink 14.
Liquid can very effectively be atomized by, e.g., introducing the liquid with the air at inlet 36 or through holes 22, or by causing the stream leaving the nozzle to impinge upon the liquid, even at a distance of several inches or more.
Other embodiments will occur to those skilled in the art and are within the following claims.
What I claim is:
