TPFSE

Objective:

vortex

• Address the design and performance of passive two-phase flow separator technologies.

• Determine range of flow rates for acceptable performance.

• Quantify the effect of fluid properties and separator geometry.

• Determine separator response and stability envelope to startup, shutdown and liquid slugging conditions.

Relevance/Impact:

• Gas-liquid separators are targeted for use in Active Thermal Control Systems (ATCS) and Advanced Life Support (ALS) applications

• Prevent degraded performance or shortened life for components that accept a single phase input, i.e., centrifugal pumps and compressors.

• Passive separation is highly reliable and consumes minimum power.

Development Approach:

• Design and build experiment package that can meter air and water into test articles.

• Two different design concepts (one specified by each PI team) for cyclonic separators will be tested.

• Technology customer co-I will specify minimal design performance parameters.  PI’s will have opportunity to expand that performance envelope.
