【Abstract】 Premixed combustion in inert porous media has the advantage of high burning rate, high combustion efficiency, uniform temperature distribution, wide lean flammable limit, energy saving and low pollutant emission. The principle and characteristics of this technology were introduced, including unidirectional flow combustion and reciprocating flow combustion. The flame propagation characteristics were discussed in detail, such as flame propagation, flame stabilization, flame instabilities, and the factors affecting flame propagation. The physical models, control equations, boundary conditions, reaction mechanism and solution methods used in numerical simulation were reviewed. The application of premixed combustion in inert porous media was also summarized. Some problems need to be studied further were pointed out.更多还原
