초록

본 연구에서는 현대적 전기식 기폭관의 해석 모델링을 대상으로 실용적 적용이 가능한 금속성 플라즈마 조성비 및 전기전도도 계산모델이 제시되었다. 현 플라즈마 모델은 기폭관 브릿지 전기폭발 현상 시 발생하는 고밀도 플라즈마 영역의 비이상 플라즈마 효과 보정을 포함하였다. 구리 플라즈마를 대상으로 한 계산 결과는 넓은 온도 범위 및 고밀도 영역에서 해당 측정 결과와 전반적으로 잘 일치하여 기폭관 모델링 대상 적용에 적절함을 보여주었다.

This study introduces the calculation model of ionization composition and electrical conductivity for metallic plasma for practical application to modeling and simulation of modern electrical detonators. The present model includes the correction for non-ideality of dense plasma conditions which are expected in electrical explosion of bridge in detonators. The computational results for copper plasma show favorable agreement with experimental data for a wide range of plasma temperature and high density conditions and the model is proper for detonator modeling with good prediction accuracy.
