N2 - A single element lean direct injection (LDI) module with convergent outlet is proposed to improve the spray distribution and combustion performance for LDI combustor. The experiments of fuel spray characteristics were conducted under different swirl intensity (S32, S38, S45) and air flowrate (0g/s, 3.3g/s, 5.2g/s, 6.8g/s). The experimental results show that the nozzle flow number of the swirler S38 is larger than that of the swirler S32 and S45, and the nozzle flow number decrease slightly when air is added. With the increase of swirl intensity, the spray cone angle increased significantly. The drops size of spray is decreased with the increase of swirl intensity and air flowrate, and the effect of air flowrate on fuel atomization quality is much greater than swirl intensity.
