Numerical modelling for multicomponent diffusion in laminar hydrogen jet flame by using opensource OpenFOAM

오픈 소스 OpenFOAM을 이용한 층류 수소 제트 화염장 내의 다종 확산 수치해석 모델 개발

The present study focuses mainly on modeling the ordinary diffusion flux of species. According to CHEMKIN, both the mixture-averaged approach, Fick's formula, and the full multicomponent approach are implemented in the framework of opensource OpenFOAM. Also the Stefan-Maxwell approach is coded and validated together against measurements of laminar hydrogen jet flame. In the case of viscosity and conductivity of mixture, the mixture-averaged approach is applied and thermal diffusion is not considered in this work. Results show that there are no distinct deviations in three different approaches of diffusion of species in the present hydrogen flame condition.
