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.
