  • A central igniter tube was designed according to engineering requirements and firing tests were completed. By considering the large length-to-diameter ratio and consolidated charge of the designed igniter tube, a one-dimensional, two-phase flow model was developed to numerically simulate the combustion process of the gas-solid two-phase flow. The simulated results are consistent with the measured ones. So the developed two-phase flow model can correctly describe the actual physical process and the parameters used in the program are reasonable. The calculation program can provide a theoretical guidance for the ignition performance analysis and optimal design of the igniter tube in different construction measurements and charge conditions. The ignition performances of the igniter tube were also analyzed on the basis of the computational results, which providing reference for the optimal design in further work.
