OpenFOAM을 이용한 난류연소현상 해석 및 내연기관에의 적용

OpenFOAM(Open Field Operation And Manipulation) is based on the object oriented language and has been developed as an alternative to commercial CFD tools for industrial application. The advantages of open source CFD allow users to create a more extensive and customized code according to users needs, whereas the commercial tools have difficulty to add or modify any user defined code. To perform IC engine simulation an automatic mesh motion algorithm is built into OpenFOAM. OpenFOAM also provides users with many solvers such as heat transfer and multi phase flow with combustion. In this study simulation of sydney bluff-body HM1 flame, IC engines and gas turbine combustion were performed by OpenFOAM to analyze the turbulent combustion problems. The PaSR(Partially Stirred Reactor) model was applied for a CI engine and gas turbine, while the b-Ξmodel was applied for an SI engine. Results were compared with measurements for some typical test cases.
