Abstract
A micronozzle device can include at least two layers stacked together to form a nozzle array. Each layer can include a plurality of microchannels that have inlet ports and exit ports. The exit ports can be oriented substantially perpendicular, parallel, or in the general direction of a central fluid flow pathway.
Claims30
A micronozzle device comprising:
- at least two layers stacked together to form a nozzle array, one or more of the layers comprising a plurality of microchannels that have at least one inlet port and a plurality of exit ports, the exit ports being adjacent to a central fluid flow pathway,
- wherein the central fluid flow pathway is defined by an annulus of the nozzle array, and the exit ports of the nozzle array face the central fluid flow pathway.
A micronozzle device comprising:
- a plurality of nozzle arrays spaced apart from one another to form a secondary pathway therebetween, each nozzle array comprising a plurality of microchannels that have an inlet port and an exit port, the exit port being oriented substantially parallel to a central fluid flow pathway,
- wherein fluid flowing in the central fluid flow pathway can enter the secondary pathways and pass between the plurality of spaced apart nozzle arrays.
A micronozzle device comprising:
- an air plate having an air inlet, an air header microchannel, a plurality of exit ports, and a plurality of vias, the air plate being configured to receive air through the air inlet and deliver the air through the air header microchannel to the plurality of exit ports;
- a fluid plate having a fluid inlet and a fluid header microchannel, the fluid plate being configured to receive fluid through the fluid inlet and deliver the fluid to the air plate through the plurality of vias formed in the air plate,
- wherein the air and fluid plates are stacked together to form a nozzle array and the exit ports are oriented to exit into a central fluid flow pathway.
