PMD 산업에서 주로 사용되는 ZPP와 <TEX>$BKNO_3$</TEX>에 대한 연소 모델링을 수행하였다. 구성방정식으로는 Saint Robert's law와 에너지보존식, 그리고 Noble-Abel 상태방정식을 사용하였다. 구축된 연소 모델과 실제 CBT에서 얻은 압력 결과데이터를 비교하였다. ZPP의 경우, 모델이 실험 결과와 유사한 압력곡선을 예측하였지만, <TEX>$BKNO_3$</TEX>는 챔버의 부피가 작을 때 모델이 실험보다 큰 최대압력을 도출하였다. 이에 대해 <TEX>$BKNO_3$</TEX>의 미연소성을 고려하였다. In this study, combustion modeling of ZPP and <TEX>$BKNO_3$</TEX> mainly used in the PMD industries has been performed. Saint Robert's law, energy conservation equation, and the Noble-Abel equation of the state have been used for governing equations. The results of pressure obtained from established combustion models and actual CBT have been compared. In the case of ZPP, the model has predicted a pressure curve similar to that of the experimental results, but <TEX>$BKNO_3$</TEX> has showed that the maximum pressure of the model is greater than the experiment at small chamber volume. For these gaps, the probability of <TEX>$BKNO_3$</TEX> unburning has been considered.
