Abstract
A fluid control device includes a housing, a fluid channel defined within the housing, the fluid channel having an inlet, and a flow control body disposed in the fluid channel, the flow control body tapering towards the inlet. The flow control body, in use, causes a fluid flowing through the fluid channel to flow into an annular fluid flow path within the fluid channel. The annular fluid flow path has a geometry selected based on a subcool of the fluid at a pressure of the fluid entering the fluid channel, and the geometry is selected to induce cavitation of the fluid to choke fluid flow through the fluid channel.
