초록

상용 CFD 소프트웨어 FLUENT를 이용하여 혼합탱크 내에서 DME와 Propane 두 가지 액화연료의 혼합에 대한 시뮬레이션을 수행하였다. 직경 1 m, 높이 2.5 m의 3D 혼합탱크를 모사하고 혼합탱크 상부에 DME가 146 l, 하부에 프로판 770 l가 존재하는 초기조건을 설정하여 34시간 동안 시뮬레이션을 진행하였으며, 시간대별 혼합 및 유동특성에 대하여 알아보았다. 혼합연료는 약 24시간 경과 후 3 mol% 범위 내에서 균일하게 혼합되었으며, 34시간 경과 시 1 mol% 내에서 균일하게 혼합되었다. 4시간 이후의 시뮬레이션 결과는 한국가스공사에서 수행된 DME 연료 실증 시험연구 기술개발 실험결과와 상당히 일치함을 확인하였다.

In this study, CFD simulation was performed with commercial CFD code FLUENT for the 3D mixing tank model (1 m in a diameter and 2.5 m in a height) of DME-Propane liquified fuels. Initial condition set-up with existence of DME 146 l at the upper side of mixing tank and Propane 770 l at the lower side of mixing tank. Characteristics of mixture and fluid flow were observed for 34 hours simulation. Two liquid fuel were uniformly mixed within range of 3 mol% after 24 hours, and range of 1 mol% after 34 hours. The simulation result following 4 hours was verified with KOGAS experimental data.
