本文在原始BDP多火焰燃烧模型的基础上,对多分散的氧化剂颗粒和扩散火焰距离进行了简化计算,对含铝和含催化剂的计算亦进行了简化处理。设计的程序较为简短,能在带FORTRAN语言的各种类型微型机上实行快速运算,计算与实测结果的对比,其精度在10％以内。理论计算还预示:凡能增大AP焰反应速度的燃速催化剂,具有大幅度提高燃速和降低压力指数的效果;选择的氧化剂颗粒级配若D(相当)接近80微米时,能达到提高燃速与降低压力指数的作用。
Based on the original BDP multi-flame combustion model, this paper simplifies the calculation of the distance between polydisperse oxidant particles and diffusion flame, and also simplifies the calculation of aluminum-containing catalyst. The design procedure is relatively short, fast calculation can be carried out on various types of microcomputers with the FORTRAN language, the calculation and the measured results compared with the accuracy of less than 10%. The theoretical calculation also predicts that any burning rate catalyst capable of increasing the AP flame reaction rate has the effect of significantly increasing the combustion rate and decreasing the pressure index; the selected oxidizer particle gradation can achieve an increase as D (quite) approaches 80 microns Burning speed and reducing the role of pressure index.
