CE-5B-2 Facility Description
CE-5B-2 is one of the two test stands in the CE-5B facility and can be configured to study lean-premixed-prevaporized (LPP) and Lean-direct-injection (LDI) concepts for developing a low NOx combustor for high speed research and advanced subsonic applications. The non-windowed combustion flametube can use a three inch square cross-section or a three inch diameter round section and has six ports available for gas sampling probes. The windowed combustion flametube takes advantage of the flat walls on a three inch square cross-section to install optical windows for non-intrusive measurements. Tests are conducted with combustion air inlet pressure ranging from 10 to 15 atmospheres with preheater and exhaust conditions described for CE-5B-1.

CE-5B-2 Special Features
The same laser based non- intrusive diagnostics of reacting and non-reacting flowfields described for test position CE-5B-1 are available to this test section. A typical data acquisition system, is used for both test positions in CE-5B; in addition, most of the optical diagnostic instruments have their own data acquisition systems.
