초록

본 연구에서는 VOF 기법을 이용하여 3D 그레인 형상의 연소표면적을 계산하는 프로그램을 개발하고 연소표면적 결과를 이용하여 내탄도 성능해석을 수행하였다. 연소표면적 계산 수행 시 격자 크기, 난류화염속도, 단위 계산시간을 기초로 한 매개변수의 의존성을 확인하고, 상용 3D 모델링 소프트웨어를 이용하여 산출한 면적 결과와 비교하였다. 개발 프로그램으로 산출한 연소표면적 결과를 바탕으로 고체로켓모터의 내탄도 해석을 수행하였다. 임의의 추진제 조성으로 화학평형을 계산하고 시간에 따른 연소표면적 및 모터 내부 압력을 예측하였다. 웹(web) 연소 동안 평균 압력은 5.34 MPa 으로 기존 연구 결과와 약 20%의 차이를 보였다.

In this study, Burning Area Analysis Program (BAAP) was developed by using VOF method to estimate the burning area of 3D shaped grain. The parametric study of mesh size, burning rate and time interval for numerical calculation was conducted. The result of BAAP is compared with the one from commercial 3D modeling software. Also the internal ballistic analysis was performed using the result of BAAP. In order to estimate the burning area and internal pressure with time, Chemical Equilibrium Analysis (CEA) was conducted with a composition of reduced smoke propellant. As a result, the web-averaged pressure was 5.34 MPa which is similar to the published research result.
