Implementation and evaluation of the dynamic Smagorinsky model and an Eddy dissipation model with multiple reaction time scales in FireFOAM

The implementation of the dynamic Smagorinsky model and an Eddy Dissipation Model (EDM) with multiple reaction time scales in the CFD code FireFOAM is presented and the newly implemented models are evaluated against two well-characterized experimental test cases: Shabbir's (1994) experiments on a turbulent buoyant plume and McCaffrey's (1979) experiments on small-scale fire plumes (14.4-57.5 kW). Overall, the numerical results show very good qualitative and quantitative agreement when compared to some of the standard models available in the code, for both the experimental test cases considered. These developments aim to supplement the available models of FireFOAM and to enhance the code's predictive capabilities of simulating fire-related scenarios.
