Phase Separator in Operation

The vortex separator developed at Texas A&M and licensed to Advanced Cooling Technologies is a passive device with no moving parts that relies on the momentum of the incoming fluid to produce a rotational flow within the device. The flow field produces a radial acceleration that drives the separation process which can acheive high throughput compared to capillary devices. Videos of the device operating under Earth-g and during NASA reduced gravity aircraft testing show how the acceleration field can be designed to operate against gravity or to minimize the pumping power under zero gravity conditions. Another design feature is that the liquid inventory can change by controlling the gas volume within the separator which allows the device to both separate and serve as an accumulator. This feature makes the separator ideal for the DoVR radiator system since liquid and gas must be exchanged between the separator and selected radiator segments.
