在价电子燃烧模型的基础上,运用分形理论建立了一个崭新的固体推进剂价电子-分形燃烧模型。针对AP颗粒形状不规则的特点,引进分形维数,进行了燃烧模拟计算方法的有关公式推导和编程计算研究,用价电子-分形燃烧模型编制出燃速计算软件。计算结果表明,该模型比价电子模型计算结果更接近实验值,这说明新型的价电子-分形燃烧模型更合理。
Based on the valence electron combustion model, a new solid-propellant valence electron-fractal combustion model was established by using fractal theory. Aiming at the irregular shape of AP particles, the fractal dimension was introduced and the formulas of calculation and calculation of combustion simulation were studied. The software of burning rate calculation was developed by using the e-fractal combustion model. The calculation results show that the model is closer to the experimental value than the calculated result of the electronic model, which shows that the new type of valence electron-fractal combustion model is more reasonable.
