This variation in ventilation is often accomplished in the course of air flow-controlled conditions, which results in the HRR to raise within the compartment and brings about combustion anywhere the combination of UHCs and oxygen is adequate and which the mixture be in website a sufficient temperature to initiate combustion (Madrzykowski and Kerber 2009; Kerber and Walton 2005).
