Abstract

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.

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.
