December 2011 – A series of four NASA Glenn experiments will be conducted
in the MSG glovebox during the first half of 2012. The Structure & Liftoff
In Combustion Experiment (SLICE)
is expected to begin in January, where the final tests will be for the Smoke
Point In Coflow Experiment (SPICE)
which first operated in 2009. These gas-fueled investigations will be followed
in the spring by the Burning And Suppression of Solids (BASS)
experiment which uses the same experimental hardware (built for SPICE). This
trio of combustion investigations should be followed in the summer by a fluid
physics experiment, Investigating the Structure of Paramagnetic Aggregates from
Colloidal Emulsions (InSPACE-3)
which last operated in 2009.
Smoke Aerosol Measurement Experiment (SAME)
Spacecraft smoke detectors must detect different types of smoke. For example, hydrocarbon fuels typically produce soot and plastics produce droplets of recondensed polymer fragments. While paper and silicone rubber produce smoke comprised of liquid droplets of recondensed pyrolysis products. Each of these materials produces a different type of smoke, with particles of various sizes and properties.
SAME will assess the size and distribution of smoke particles produced by different types of material found on spacecraft such as, Teflon, Kapton, cellulose and silicone rubber. SAME will evaluate the performance of the ionization smoke detectors (used on Space Shuttles), evaluate the performance of the photoelectric smoke detectors (used on the ISS) and collect data for which a numerical formula can be developed and used to predict smoke droplet growth and to evaluate alternative smoke detection devices on future spacecraft.
Smoke Aerosol Measurement Experiment-R (SAME-R)
The Boiling Experiment Facility (BXF)
Boiling Experiment Facility (BXF) will accommodate two
separate investigations, BXF–MABE (Microheater Array
Boiling Experiment) and BXF–NPBX (Nucleate Pool Boiling
Experiment), to examine fundamental boiling phenomena.
BXF is planned for the Microgravity Science Glovebox (MSG)
located in the U.S. Laboratory on the International Space
Station (ISS). The purpose of the BXF is to validate models
being developed for heat transfer coefficients, critical
heat flux, and the pool boiling curves.
Investigating the Structure of Paramagnetic Aggregates From Colloidal Emulsions (InSPACE) -2, -3
is a microgravity fluid physics experiment that will be performed
on the International Space Station (ISS). The purpose of
this investigation is to obtain fundamental data of the complex
properties of an exciting class of smart materials termed
magnetorheological (MR) fluids. MR fluids are suspensions
of small (micron-sized) superparamagnetic particles in a
nonmagnetic medium. These controllable fluids can quickly
transition into a nearly solidlike state when exposed to
a magnetic field and return to their original liquid state
when the magnetic field is removed. Their relative stiffness
can be controlled by controlling the strength of the magnetic
field. Due to the rapid-response interface that they provide
between mechanical components and electronic controls, MR
fluids can be used to improve or develop new brake systems,
seat suspensions, robotics, clutches, airplane landing gear,
and vibration damping systems.
Shear History Extensional Rheology Experiment (SHERE)
resistance of a fluid to an imposed flow is termed a ‘viscosity’,
and is a fundamental material parameter by which manufacturers
and end-users characterize a material. Normally, researchers
will place a material in a commercial instrument that imposes
a simple shearing flow, and will report a rate-dependent
shear viscosity. While this level of characterization is
sufficient for some processes, in typical industrial polymer
processing operations, the material experiences a complex
flow history with both shear and extensional kinematic characteristics.
Shear History Extensional Rheology Experiment-II (SHERE-II)
Coarsening in Solid-Liquid Mixtures (CSLM)
Coarsening in Solid-Liquid Mixtures-2R (CSLM-2R)
Coarsening in Solid-Liquid Mixtures-2 Reflight (CSLM-2R) is a materials science
experiment that will support the development and accuracy of theoretical models
of the Oswald Ripening (coarsening) process. CSLM-2R will determine the
factors controlling the morphology of solid-liquid mixtures during coarsening.
Smoke Point in Coflow Experiment (SPICE)
The Smoke Point in Coflow Experiment (SPICE) will observe nonbuoyant round laminar jet diffusion flames in air coflow at standard temperature and pressure (STP) to:
Data to be obtained
from SPICE include video of flames, digital photographs
of flames, radiometer output, fuel flow velocity, fan voltage,
and coflow air velocity.
Structure & Liftoff In Combustion Experiment (SLICE)
Structure and Liftoff in Combustion Experiment (SLICE) is a combustion science experiment that will extend the SPICE investigation by introducing additional objectives that relate to flame stability and structure rather than the smoke point. The SLICE objectives will provide experimental results that will allow optimization of the ACME Co-flow Laminar Diffusion Flame experiment, increasing its scientific return.
Burning and Suppression of Solids (BASS)
Burning and Suppression of Solids (BASS) is a combustion science experiment that
will bridge the gap between normal gravity NASA-STD-6001 Test # 1 method, ground
based microgravity tests, and actual material flammability in microgravity. BASS
will also assess the effectiveness of an inert, gaseous extinguishing agent
(similar to that used on ISS) in putting out flames over different material,
geometries, and flow.
Capillary Channel Flow (CCF)
is a versatile experiment for studying a critical variety of inertial-capillary
dominated flows key to spacecraft systems that cannot be studied
on the ground. Applications of the results of CCF are direct to
the portion of the aerospace community challenged by the containment,
storage, and handling of large liquid inventories (fuels, cryogens,
water) aboard spacecraft. The results are immediately useful for
the design, testing, and instrumentation for verification and validation
of liquid management systems of current orbiting, design stage,
and advanced spacecraft envisioned for future lunar and Mars missions.
The results will also be used to improve life support system design,
phase separation, and enhance current system reliability by designing
into the system passive, in this case capillary redundancies.
Zero Boil-Off Tank Experiment (ZBOT)
ZBOT research will aid the design of long-term storage systems for cryogenic fluids. Simulated by Perfluoro-normal-Pentane (P-n-P).
Observation and Analysis of Smectic Islands in Space (OASIS)
The Observation and Analysis of Smectic Islands In Space (OASIS) experiment is designed to exploit the unique characteristics of freely suspended liquid crystals in a microgravity environment to advance the understanding of fluid state physics.
OASIS is being developed under contract by ZIN Technologies, Inc. The OASIS sample module flight hardware will be developed from a functional model of the liquid crystal mixture dispensing system from commercial off the shelf (COTS) parts and will be designed to be integrated into the Microgravity Science Glovebox (MSG).
Packed Bed Reactor Experiment (PBRE)
The Packed Bed Reactor Experiment (PBRE) is being developed under
the Space Flight Systems Development and Operations Contract (SpaceDOC),
through the collaboration of ZIN Technologies and the National Aeronautics
and Space Administration (NASA) Glenn Research Center (GRC), the
International Space Station (ISS), the University of Houston, the
National Center for Space Exploration Research (NCSER) and NASA Johnson
Space Center (JSC). PBRE is an ISS payload designed to validate the
hydrodynamics of two phased flow in a packed bed reactor operating
within a microgravity environment. Packed bed reactors will be used
of future space missions to purify water and air, two substances
essential for human life.
Foam Optics And Mechanics (FOAM)
The objective of the FOAM (Foam Optics And Mechanics) flight experiment is to
study the characteristics of wet foams in the absence of gravity. The microgravity
environment on the ISS will eliminate drainage of liquid out of the wet foams
at high liquid contents. This experiment is a joint collaborative project
between the European Space Agency (ESA) and NASA. As part of the ISS Non-Exploration
Program, Professor Douglas Durian, University of Pennsylvania, Department
of Physics, participates as the U.S. principal investigator, and is supported
by NASA. Professor Dominique Langevin of the University of Paris South (UPS)
leads the flight project. As part of the international science team, ESA
also supports several additional scientists from Germany, Ireland, France,
Belgium and Sweden, mostly from universities.
