Abstract
Pulse combustion as an advanced combustion has many advantages, such as high combustion efficiency, low pollution emissions. Due to the complex mechanism of pulse combustion, narrow adjustment range of load, it is difficult to achieve a large-scale application. For this reason, the pulse combustion process is investigated by means of simulation in this paper, and the effects of some parameters on the combustion process are analyzed including the inlet pressure, excess air ratio, decoupling chamber pressure and wall temperature of the combustion chamber. The results indicate that the stable pulse combustion could be produced in the combustor when the temperature of the combustion chamber is from 800k to 1400k. With the excess air coefficient increased, the pulsation frequency gradually decreases. As the excess air coefficient or inlet pressure increases, the pressure in the combustor gradually increases. The combustor performance could be controlled by adjusting the decoupling chamber pressure.
