【 摘 要 】

Numerical simulations of radiation received from a fire front were carried out in a situation of laboratory-scale fire. The fire front was determined at different instants based on camera images taken during a real experiment, and predicted in using a "small world network" propagation model. The fluxes were computed using either a ray tracing method with EDStaR, or a home-made reciprocal Monte Carlo method. Results were compared with available flux measurements using radiative heat flux gauges.
