Two-Phase Flow Separator Experiment
(TPFSE)
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.
