This Conference pertains to
thermophysical research and technology considered to be important for
emerging aerospace applications. Sessions focus on scientific and
technology research efforts originating from government, university and
commercial research programs. The Conference starts with a session on
emerging, and perhaps controversial, thermal control issues, which is
followed by discussions on recent progress in fundamental research
topics, and then the discussions move on to specific new technologies
and applications. Technology discussions focus on; single and two-phase
flow technologies, advanced thermal control coatings, convection
interfacial mass transfer, and innovative thermal control devices for
spacecraft applications.

Recent space initiatives are considering the use of high power density
electronics, advanced lasers and nuclear electric propulsion. The power
levels that future spacecraft will be dealing with are changing the
order of magnitude from kilowatts to hundreds of kilowatts and even
more. This change requires some fundamental revision of the Thermal
Control System design approach. As there is only one way to get rid of
the waste heat in space, to reject it via radiation, the radiator areas
will increase so dramatically that they will start dictating application
limitations and architecture. A global project such as Prometheus is an
excellent example of the case when the heat rejection system is
comparable and even exceeds the payload in weight and envelope. Papers
in this session will describe different efforts and approaches to create
advanced thermal control systems designed for large transport capacity
and high heat flux applications. Examples are high transport/high
temperature loop heat pipes, high heat flux/high temperature cooling
loops and evaporators, and hybrid pumped fluid loops.
B05. Advanced Thermal Control Technologies via Conduction, Convection,

Two-phase technologies have become the
standard tools for spacecraft thermal control. Papers are invited that
discuss either recent advancements in these established technologies or
address emerging techniques: Examples are: phase-change and sensible
heat thermal storage, heat pumps, high conductivity structures and
substrates, thermal switches, novel radiator concepts, and single-phase
mechanically pumped technologies. Papers on issues/scalability of high
power thermal systems in microgravity are also invited.

analysis, testing, and advanced technologies for lunar, planetary, and
deep space missions. Advanced concepts such as autonomous thermal
control and thermal energy management based thermal control are also
solicited.

Papers in this session will concentrate on spray cooling research which
addresses fundamental thermophysics cooling system design for
ground-based, airborne and space applications and platforms. Topics of
interest include evaporator design, alternative fluids, large surface
area (> 2 cm2) studies, scalability, nozzle design and enhancements to
spray cooling.
The next generation of airborne and space based platforms include the
development of alternative power systems, advanced Lasers and electronic
components. On-board components such as Laser-Diode Arrays (LDA’s) and
Multi-chip modules (MCM’s) require high heat flux thermal management
techniques. Technology requirements for these systems include the
cooling of high flux heat sources (≥ 100 W/cm2), while maintaining tight
temperature control (approx. +/- 2 oC), reliable start-up, shut down,
and long term stability. Spray cooling provides the potential for high
heat flux (HHF) cooling upwards of 100 W/cm2 using fluorinerts and 1000
W/cm2 for water. It allows for tight temperature control at low coolant
fluid flow rates. Spray cooling is one of the most appealing heat
acquisition techniques for the thermal management needs of tomorrow’s
HHF systems.

In-situ Resource Utilization (ISRU) for
lunar and other extraterrestrial missions will require novel concepts
