Pressure Dynamic Distribution in Reciprocal Porous Media Combustion System with Heat Recirculation

The characteristic of dynamic pressure wave in a novel reciprocal porous media combustion system with heat recircula- tion was studied experimentally.The effects of half-cycle,superficial velocities,secondary air ratio and porous medium structure on pressure dynamic distribution were investigated.The results show that the superficial velocities and secondary air ratio had greater influence on the pressure dynamic profiles than the half-cycle and structure factors.It was found that the dynamic pressure in the recirculation system periodically varied with rectangle waves when the system was operated steadily and periodically.These findings provide a good reference for the design,operation of the reciprocal porous media combustion system with heat recircula- tion.
