Soot Volume Fractions and Temperature In a Large Scale Pool Fire

En’Urga Inc. designed, fabricated, installed and evaluated an intrusive fiber-optic probe at Sandia National Laboratories.  The fiber optic probe is ceramic clad and water-cooled to withstand the harsh environment inside the pool fire.  Simultaneous two wavelength emission and one wavelength absorption measurements provide the soot volume fractions and temperature at specific locations with the pool fire.  A photograph of the probe can be seen under products.  The product line has since been expanded with a range of intrusive probes.  These probes enable multiple wavelength and multiple location measurements of absorption or emission inside large scale fires.  Typical users include researchers in residential/commercial fire protection engineering and combustion scientists.

Further information on the specific product (TWEAP-50-1) used at Sandia National Laboratories can be obtained from the following publication.
