The 20th Annual Thermal & Fluids Analysis Workshop (TFAWS) will be hosted by Marshall Space Flight Center in Huntsville, Alabama
Constellation Thermal Overview
NASA's mission to replace the Space Transportation System and return man to the Moon and beyond has many thermal challenges. An overview of the three major project areas currently being worked across the NASA centers and contractor workforce will be given. The specific thermal challenge areas, the thermal design approach, and the thermal tools/methods will be discussed. The overview will span all three days of TFAWS and will be broken out as follows:
Ares
- General Introduction to Ares-IX, Ares-1, and Ares-V Vehicles
- Ares-1X Overview
- Ares First Stage (Solid Rocket Motor, Aft Skirt/Thermal Curtain, Booster Separation & Tumbler Motors)
- Ares Upper Stage (Avionics Thermal Control, Main Propulsion System, Ullage Settling Motors, Roll/Reaction Control System, Common Bulkhead)
- Ares J-2X Engine
Orion
- On-Orbit Passive Thermal Control (Orion Service Module & Crew Module)
- Orion Launch Abort System
- On-orbit Active Thermal Control (Orion Service Module & Crew Module)
- Orion pre-launch Active Thermal Control
- Orion Post-Landing
Altair Lunar
- Altair Design Overview & Thermal Challenges
- Technology Development Process

Generalized Fluid System Simulation Program (GFSSP)
Instructor: Alok Majumdar, NASA/Marshall Space Flight Center
GFSSP is a general-purpose computer program developed at Marshall Space Flight Center (gfssp.msfc.nasa.gov) for analyzing steady state and time-dependent flow rates, pressures, temperatures, and concentrations in a complex flow network. This Hands-on course quickly teaches new users to use GFSSP to solve engineering flow network problems through lectures and tutorial problems. The program is capable of modeling phase changes, compressibility, conjugate (solid to fluid) heat transfer, mixture thermodynamics, pumps, compressors and external body forces such as gravity and centrifugal. The program is integrated with state of the art thermodynamic property programs for computing real fluid properties of all cryogenic propellants and commonly used fluids. GFSSP is also capable of modeling fluid components such as pipe, orifice, bends, valves, regulators and Joule-Thompson devices. The graphical user interface allows users to build their models using "point, drag and click" method. The program employs a finite volume formulation of mass, momentum, and energy conservation equations in conjunction with the thermodynamic equations of state for real fluids as well as energy conservation equations for the solid. GFSSP has been used in many NASA programs including Space Shuttle Main Engine, Space Station, and currently being extensively used in the design of Main Propulsion System of Ares I. GFSSP is available for any work supported by US Government. In TFAWS 2009, there will be two Hands-on sessions: Basic and Advance. Participants can register for one or both sessions. Participants with previous experience with GFSSP can register for Advance session.
