Abstract

In order to investigate the influence of plasma combustion on the performance of aeroengine combustor, a local geometric model of the two-head sector section of the short combustor was established. The steady-state numerical calculation of the kerosene in the combustor was carried out under the conventional mechanism and the specific operating condition under the plasma mechanism. The numerical calculation results of the combustor with or without the plasma mechanism were compared and analyzed. The results show that the average temperature, flow field velocity, density and turbulent kinetic energy behind the cyclone in the two-head fan section of the combustion chamber are better than those under the conventional mechanism, which indicates that the application of plasma mechanism can significantly improve the combustion performance of the combustion chamber to a certain extent. Under the chemical proper ratio, the average temperature of the outlet section of the combustion chamber increases from 1910 K to 2050 K, and the combustion efficiency increases from 82.4% to 90.1% by 7.7%, indicating that the addition of plasma mechanism can deepen the chemical reaction degree of kerosene and release more heat to improve the combustion efficiency of kerosene.
