| HYCOM-HC027
|
Short Description
| Combustion experiments have been carried out in nonuniform obstructed tube of 12.4 m long combined of two parts with diameter of 174 and 520 mm i.d. (Configuration 3). Obstacles spaced by tube diameter. Diameter / Obstruction (BR) for Part 1: 174 mm / 0.3, for Part 2: 520 mm / 0.6. Sonic combustion of uniform test mixture with 13% of H2 in air was investigated Ignition point is I1 (Part 1).
|
What phenomena were studied
| Effect of tube diameter change (flame propagating from less to higher tube size)
Effect of blockage ratio changes (flame propagating to the area with lower degree of obstruction)
|
What phenomena / effects can be studied
| Flame propagation in the presence of nonuniform geometry.
|
Instrumentation
| Measurements include 6 piezoresistive transducers and 16 collimated germanium photodiodes. Time resolution of 10 µs. The photodiodes were not calibrated, and they provided flame radiation intensity qualitatively.
|
Test variables
| Tube diameter, blockage ratio
|
Data description / Data completeness
| All pressure and photo-diode recordings in digital form
|
Data availability
| Publicly accessible
|
Source of data / Reference
| Technical Report: EU Project HYCOM, 2004 (to be published)
|
Why were chosen
| Very well instrumented, complete description, by the moment no similar results elsewhere are available
|
Relevance to the project purposes
| Can address separate phenomena, which are of primary interest for the project purposes
