본 연구에서는 고체연소미립자로써 탄소입자와 산화제로써 순수 산소를 사용 하였으며, 매우 높은 대류 열 전달 상태에서 탄소입자 표면의 대류 열저항과 고체 내 부의 전도 열 저항에 의하여 발생하는 탄소입자 내부의 온도구배를 고려하여 탄소입자 와 순수 산소의 혼합물에 있어서 이상 폭발현상을 수치적으로 연구하였다.
In this study the structure of a two phase detonation has been numerically investigated through the assumption of a steady and one-dimensional flow in the suspension of carbon particles and pure oxygen. The bow shock formation in front of carbon particles has been taken into consideration when the relative velocity of gas flow with respect to the particle exceeds the local speed of sound. But its effect was found to be very limited to the induction zone only. Furthermore the interior particle temperature distribution has been considered in this work. It was found that the inner temperature gradient was very steep in the region of high relative velocity. On the while the temperature distribution inside the particle was almost uniform in the region of low relative velocity. Overall, the effect of the interior particle temperature distribution has been significant in the two phase detonation.
