- Abstract
- Most previous experimental studies of radiative ignition of combustible solids were conducted with a vertically mounted sample and horizontally directed external radiation. There is little information available for other configurations. Also, most previous theoretical models of radiative ignition were one-dimensional and effects of the orientation on ignition were neglected, assumed to be negligible, or included only through convective heat loss from the sample surface. To obtain the convective heat loss from the sample surface. To obtain the effects of the sample orientation with respect to the direction of the external radiation on auto-ignition, the radiative ignition mechanism was studied experimentally under various orientations of polymethylmethacrylate (PMMA) and red oak.
