TPFSE Quad Chart
 

Objective:

•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.
•Promote enhanced phase change by removing second phase and to promote contact with heat transfer surface.

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.
