|Capability Title||Materials/Component compatibility with advanced fuels|
|Laboratory||Oak Ridge National Laboratory (ORNL)|
|Capability experts||Chris Janke, Mike Kass, Jim Keiser|
|Description||Specialized exposure chambers are coupled with advanced analytical chemistry instruments and methodologies to accurately access fuel-material interactions. Existing test chambers able to expose over 300 polymer, metal and sealant specimens simultaneously under highly controlled conditions of pressure, temperature and flow have been used to represent field conditions for determining fuel compatibility limits for government agencies, Underwriters Laboratories and private industry. Advanced analytical capabilities (which include pyrolysis GC-MS, XDS, and SEM/TEM) have provided valuable insight in the physical & chemical interactions governing compatibility. Additional capabilities include advanced rheological instrumentation to determine fuels efficacy with existing pumps and piping.|
|Limitations||Established capabilities are focused on primarily material interactions. An expensive full system (real-world) analysis (with prototype components) may be required for definitive conclusions.|
|Unique aspects||Exposure chambers can simultaneously exposure over 300 material specimens in both the liquid and vapor phase. The chamber environment can be controlled for pressure, temperature, flow rate, and the chemistry in the head space region. Pyrolysis GC-MS instrument can identify the structural changes that have occurred in polymeric materials following fuel exposure.|
|Availability||All test apparatuses are readily available.|
