A fluidic device, that operates on a pressurized liquid flowing through it to generate an oscillating spray having desired three-dimensional flow characteristics, includes a member that has fabricated within it at least two liquid flow channels that are configured in the form of a fluidic circuit having an inlet and an outlet and a centerline therebetween. These flow channels are further configured so that the straight line projections of their centerlines, that extend from their outlets, intersect at a prescribed intersection angle, Θ, and the outlets are separated by a characteristic separation distance, “w.” We have found that the values of the intersection angle, Θ, and separation distance, “w,” can be are chosen so as to yield the desired three-dimensional flow characteristics of the spray.

We claim: 1. A fluidic device that operates on a pressurized liquid flowing through said device to generate in the gaseous environment surrounding said device a three-dimensional, oscillating spray of liquid droplets having desired flow characteristics, said device comprising: a member having two boundary surfaces, wherein each of said boundary surfaces having fabricated therein a liquid flow channels, wherein each of said liquid flow channels being configured in the form of a fluidic circuit having an inlet, an outlet, a centerline and a bottom surface which extends therebetween, and a characteristic dimension “h”, wherein each of said liquid flow channels being further configured proximate said outlet of said flow channel so that said channel bottom surface and said boundary surface in which said channel is fabricated assume a continuous curvature so as to redirect the direction of said channel centerline to cause each of said channels to converge towards the other said channel while keeping said channel characteristic dimension “h” constant along the length of said channel over which said channel redirection is imposed, wherein the straight line projections of said centerlines, that extend from said circuit outlets, intersect at a prescribed intersection angle, Θ, and said outlets are separated by a characteristic separation distance, “w,” and wherein the values of said intersection angle, Θ, and said separation distance, “w,” and the configurations of said fluidic circuits are chosen so as to yield the desired flow characteristics of said spray. 2. The fluidic spray device as recited in claim 1, wherein: said member having a first and a second portion and each portion having a top and a bottom boundary surface, one of said flow channels being located proximate the top boundary surface of each of said portions, and said bottom boundary surface of said first portion and said top boundary surface of said second portion being configured so as to mate together and allow said bottom boundary surface of said first portion to form a boundary and liquid-tight seal for the top portion of the flow channel of said second portion. 3. The fluidic spray device as recited in claim 1, wherein: said member having two cavities, a pair of fluidic inserts, each of said inserts having fabricated within said insert one of said liquid flow channels, wherein each of said cavities having sidewalls that are configured to receive one of said inserts and to enclose said insert with a liquid-tight seal, wherein said cavities are further configured in said members so as to provide for said intersection angle, Θ, and said characteristic separation distance, “w”. 4. The fluidic spray device as recited in claim 1, wherein: the ratio of said characteristic dimension, “w”, to said flow channel characteristic dimension, “h”, is in the range of: w/h=1-20, and said intersection angle, Θ, is in the range of 5 to 120 degrees. 5. A method of forming a fluidic device that operates on a pressurized liquid flowing through said device to generate in the gaseous environment surrounding said device a three-dimensional, oscillating spray of liquid droplets having desired flow characteristics, said method comprising the steps of: forming a member having two boundary surfaces, fabricating within each of said boundary surfaces a liquid flow channels, configuring each of said liquid flow channels in the form of a fluidic circuit having an inlet, an outlet, a centerline and a bottom surface which extends therebetween, and a characteristic dimension “h”, configuring each of said liquid flow channels proximate said outlet of said flow channel so that said channel bottom surface and said boundary surface in which said channel is fabricated assume a continuous curvature so as to redirect the direction of said channel centerline to cause each of said channels to converge towards the other said channel while keeping said channel characteristic dimension “h” constant along the length of said channel over which said channel redirection is imposed, wherein the straight line projections of said centerlines, that extend from said circuit outlets, intersect at a prescribed intersection angle, Θ, and said outlets are separated by a characteristic separation distance, “w,” and wherein the values of said intersection angle, Θ, and said separation distance, “w,” and the configurations of said fluidic circuits are chosen so as to yield the desired flow characteristics of said spray. 6. The method as recited in claim 5, further comprising the steps of: forming said member with a first and a second portion and each portion having a top and a bottom boundary surface, locating one of said flow channels proximate the top boundary surface of each of said portions, and configuring said bottom boundary surface of said first portion and said top boundary surface of said second portion so as to mate together and allow said bottom boundary surface of said first portion to form a boundary and liquid-tight seal for the top portion of the flow channel of said second portion. 7. The method as recited in claim 5, further comprising the steps of: forming said member with two cavities, providing a pair of fluidic inserts, fabricating within each of said inserts one of said liquid flow channels, configuring each of said cavities so as to receive one of said inserts and to enclose said insert with a liquid-tight seal, and configuring said cavities in said members so as to provide for said intersection angle, and said characteristic separation distance, “w”. 8. The method as recited in claim 5, wherein: the ratio of said characteristic dimension, “w”, to said flow channel characteristic dimension, “h”, is in the range of: w/h=1-20, and said intersection angle, Θ, is in the range of 5 to 120 degrees.
