Abstract
A method and system for stabilizing flow includes introducing a flow into a channel with a minimum cross-sectional dimension of less than three millimeters and triggering a release of one or more bubbles in the flow at one or more locations in the channel. The one or more locations are spaced in from an inlet and an outlet to the channel.
Claims16
A system for stabilizing flow during flow boiling, the system comprising:
- at least one of a minichannel and a microchannel having channel walls between an inlet and an outlet defining a passage capable of receiving flow;
- a high pressure region upstream from a transition to a low pressure region within the passage;
- a low pressure zone within the passage adjacent the transition from the high pressure region to the low pressure region;
- one or more nucleation cavities having a radius within a range which satisfies criteria for nucleation located in the wall of the channel adjacent the low pressure zone fashioned to trigger a release of one or more bubbles in the flow at one or more locations in the at least one of the minichannel and the microchannel that effectively transfer heat to the flow through the wall of the channel and increase resistance to backflow in the channel and stabilize the flow.
