A new high-irradiation ignition test and diagnosis method of solid combustibles

This study proposes a new high-irradiation ignition test method for studying the pyrolysis and of solid combustibles under extreme scenarios (> 0.1 MW?m-2). The irradiation system that generates 10-cm octagonal spot dynamic with peak flux 1.25 MW?m-2 95% uniformity, chamber well-controlled ambient conditions advanced diagnostics coupled multi-physical parameter measurement system. A verification was conducted on corrugated cardboard using proposed method, resulting in high-quality outcomes lower coefficients variation compared to previous methods. improved approach provides better procedure testing understanding threshold combustible materials laying foundation development models material processes high irradiation.
