Definitions
- the ligaments into relatively large drops through atomization, and break the large drops into smaller droplets through secondary atomization
- the droplets become smaller than 100 micrometers, they become harder to break, and secondarv atomization typically ceases, thus preventing most of the droplets from becoming as small as 10 micrometers
- the bulk liquid is much larger than the desired droplet size and therefore, i must be broken down a number of times to become relatively small, the droplets ultimately formed by conventional devices will have a relatively wide size range
- the invention provides a method of atomizing a liquid, comprising the steps of flowing a liquid over an atomizing edge of an orifice, and flowing a gas against the liquid to cause atomization of the liquid into droplets having a Sauter mean diameter smaller than 35 micrometers at a gas-liquid mass ratio of less than or equal to 0.2

- FIG 34 is a sectional view of the seventeenth embodiment taken along line 34-
- the four inner surfaces of the third opening 56 diverge ir the flow direction. These diverging inner surfaces decelerate the main gas, which provides a less turbulent spray plume.
- the atomizing edges 62 on the inner surfaces of the second opening 54 are preferably separated by a width of not more than 250 micrometers, which concentrates the gas flow at the atomizing edges 62 where the gas interacts most strongly with the liquid.
- the ratio of the smallest atomizing perimeter (i.e., the k" ⁇ gth of an atomizing edge in an orifice) of the second opening 54 to cross-sectional area of the second opening 54 in the plane of that perimeter is preferably at least 8,000 meters '1 , which improves atomization efficiency and lowers the gas-liquid mass ratio
- the first and second layers 42 and 44 form two sets of liquid orifices and channels 64 that each supply liquid to be atomized onto the respective inner surfaces of the second opening 54
- the liquid forms thin films having substantially uniform thicknesses at the exit of the liquid orifices 64
- the liquid film is further thinned as it is drawn over the inner surfaces of the second opening 54
- the liquid orifices and channels 64 can be formed by providing cavities in the first layer 42, the second layer 44, or both
- Liquid forced through the liquid orifices 64, at a flow rate of, for example, 5 milli ters per minute, will form thin films on the inner surfaces of the second opening 54
- the thin films of liquid are drawn, and further thinned, by the high-velocity gas flow to the atomizing edges 62.
- the main gas forced through the main gas supply orifice 60, at a flow rate of, for example, 5 liters per minute, breaks the liquid into ligaments and breaks the ligaments into droplets through primary atomization
- the atomizing device preferably also includes two sets of auxiliary gas orifices and channels 66, one on each side of the main gas orifice 60, which are formed by the first, second, and third layers 42, 44, and 46
- the auxiliary gas orifices and channels 66 can be formed by providing cavities in the first layer 42 and the second or third layer 44 or 46, or both
- the auxiliary gas orifices 66 supply high-velocity gas to the atomizing edges 62
- the auxiliary gas orifices and channels 66 are designed so that the auxiliary gas does not become turbulent under standard operating condi ons
- auxiliary gas Gas forced out of the auxiliary gas orifices 66, at a flow rate of, for example, 1 liter per minute, impinges on the liquid at the atomizing edges 62, effectively pinching the liquid between the main and auxiliary gas flows
- the auxiliary gas thus aids the main gas in the formation of ligaments at the atomizing edges 62 by preventing liquid accumulation on the downstream side of the atomizing edges 62 and by shearing off the liquid between the main and auxiliary gas flows, forming fine ligaments
- the third layer 46 is also etched in the same manner as the first layer 42 to form the third opening 56 and a portion of the auxiliary gas orifice and channel 66
- FIG 1 shows a presently preferred arrangement for providing the main gas, auxiliary gas, and liquid to the atomizing device
- This arrangement includes a submount 68 and a distribution device 70
- FIGS. 5 to 12 show embodiments of atomizing devices that are similar in many respects to the first embodiment shown in FIGS. 1 to 4. Differences between these embodiments and the first embodiment are described below.
- FIGS. 5 and 6 A second embodiment of an atomizing device 80 is shown in FIGS. 5 and 6.
- the inner surfaces of the first opening 52, the third opening 56. and all the inner surfaces forming the orifices and channels 66 and 64 of the first layer 42 extend substantially parallel to the flow direction Since the inner surfaces of the third opening
- Liquid forced through the liquid orifices 1 16 at, for example, a flow rate of 10 milliliters per minute per square millimeter of surface occupied by the array of orifices will move across the surface of the second layer 104 to atomizii'L edges 124 of the gas orifices 1 10.
- Liquid forced through the liquid orifices, at a flow rate of, for example. 10 milliliters per minute per square millimeter of spray array area, will move through the pathways 139 between the second and third layers 104 and 108 to atomizing edges 124
- Liquid forced through the liquid orifices 1 16 at, for example, a flow rate of 10 milliliters per minute per square millimeter of spray array area, will move across the surface of the second layer 104 to atomizing edges 124 of the gas orifices 1 10
- Liquid forced through the liquid orifices 1 16 at, for exa i.ple, a flow rate of, for example, 10 milliliters per minute per square millimeter of the spray array area, will move across the surface of the first layer 102 to the entrances of the gas orifices 1 10.
- the atomizing device includes a connection block 158, a substantially planar filter layer 160, a substantially planar first layer 102, and a substantially planar second layer 104.
- first layer 102, and second layer 104 preferably has a length and a width determined by the desired liquid atomization rate (based on a chip rating such as 10 milliliters per minute per square millimeter of orifices), and a thickness within the standard range for silicon wafers (e.g., 500 micrometers) used for bulk micromachining (although the first layer is preferably made of PYREX)
- Each of these channels 170 has filter pores 173 at its inlet.
- These filter pores 173 can, for example, be circular or square, and preferably have widths of less than or equal to 1/3 of the width of the liquid orifices 1 16 As shown in FIG. 34, the filter pores 173 can be flushed by flowing fluid into the liquid pert 120 and through a flushing port 172 During normal operation, this flushing port 172 is closed, unless a recirculating liquid pump system is used.

- the inner surfaces of the first layer 102 which is formed of PYREX, are preferably formed by ultrasonic machining.
- the filter, first, and second layers are then aligned and connected by anodic bonding, which is a preferred process for connecting silicon to PYREX.
- the gas and liquid ports 1 18 and 120 of the connection block 158 which is made of steel, are preferably formed by common machining methods, and the plenum, first, and second layers are then connected to the connection block through O-rings 164 and 168 (or a sealing gasket) to form the atomizing device Having described preferred implementations of the invention, it is appropriate to address principles underlying the foregoing and other implementations of the invention
- CD drag coefficient of a droplet having a diameter equal to the critical diameter
- p A density of the gas and U R : relative velocity between the droplet and the gas.
- Primary atomization yielding droplets smaller than the critical diameter occurs because of the thinness of the liquid at the atomizing edge. This results in a somewhat smaller average droplet size, and also in a narrower droplet size distribution.
