Assessing computational models: case studies in turbulent combustion
Abstract
In most applications, combustion happens in a turbulent environment. To model such a phenomena with so-called large-eddy simulations, we use mathematical constructs called turbulent-combustion models. Variations of these models abound and there is demand for more. However, the analysis of about forty studies in Gonzalez-Juez et al., Prog. Energy Combust. Sci., 2017 shows that determining how to fairly assess these models and how to use them in practice are important tasks that have been overlooked. In this talk, I support this statement by discussing selected results from this paper as well as newer results. In doing this, I identify several questions --none of them new-- that those of us developing or using turbulent-combustion models should ask themselves.
