Abstract
Mulch is commonly found near buildings and is a useful surrogate to study various fuels that may be present near buildings. To this end, mulch beds were exposed to continuous, wind-driven firebrand showers. These experiments build on our prior work where mulch beds were installed adjacent to realistic-scale reentrant corner assemblies. As a result, a complete data set of firebrand mulch ignition has been collected, both for mulch beds located adjacent to realistic-scale building components, and far simpler singular mulch beds with no walls present. The mulch beds were exposed to continuous firebrand showers generated by the continuous feed firebrand generator. The sustained flaming ignition of mulch beds were observed up to 86 % MC under 8 m/s wind speed. The number of firebrands decreased for lower MC cases as the applied wind speed increased. Such information is critical understand fundamental mulch ignition behavior and is also of great use for mulch test standard development.
