MICRONOZZLE ATOMIZERS AND METHODS OF MANUFACTURE AND USE

摘要

A micronozzle device can include at least one layer having a plurality of nozzle exits for delivering a mixture of a first fluid and a second fluid, at least one first-fluid header layer having a plurality of first microchannels for receiving the first fluid, at least one first-fluid via layer adjacent the at least one first-fluid header layer to receive the first fluid and direct it to respective ones of the plurality of nozzle exits, at least one second-fluid header layer having a plurality of second microchannels for receiving the second fluid, at least one second-fluid via layer adjacent the at least one second-fluid header layer to receive the second fluid and direct it respective ones of the plurality of nozzle exits, and a plurality of first curtain-gas nozzles located at a first side of the micronozzle device and a plurality of second curtain-gas nozzles located at a second side of the micronozzle device.

1. A micronozzle device for delivering a plurality of fluids, comprising:
at least one layer comprising a plurality of nozzle exits for delivering a mixture comprising a first fluid and a second fluid; at least one first-fluid header layer having a plurality of first microchannels for receiving the first fluid; at least one first-fluid via layer adjacent the at least one first-fluid header layer to receive the first fluid and direct it to respective ones of the plurality of nozzle exits; at least one second-fluid header layer having a plurality of second microchannels for receiving the second fluid; at least one second-fluid via layer adjacent the at least one second-fluid header layer to receive the second fluid and direct it to respective ones of the plurality of nozzle exits; and a plurality of first curtain-gas nozzles located at a first side of the micronozzle device and a plurality of second curtain-gas nozzles located at a second side of the micronozzle device, the first and second curtain-gas nozzles being sized to deliver air therethrough to define boundary layers that restrict the flow of the mixture of the first and second fluids after exiting the plurality of nozzles.
