Heat release process in three-dimensional macro-cellular SiC reactor under Diesel engine-like conditions

► Combustion reactor heat capacity significantly influences the thermodynamics of the process. ► Low- and high-temperature oxidation in a porous reactor is much faster with shorter delay time. ► Combustion temperature and pressure peaks are significantly reduced in porous reactor. ► Qualitative similarity of heat release process under Diesel and in porous reactor conditions.
