This paper applies the Eulerian stochastic field method to the solution of the subgrid joint probability density function (PDF) of the reacting scalars in a large eddy simulation (LES) of a jet of hydrogen issuing into a coflow of vitiated air. The hot co-flow induces autoignition of the mixture and a lifted flame results downstream of the nozzle exit. The simulations were performed using a detailed H 2 -air mechanism. The results were found to be sensitive to the co-flow temperature even with temperatures va…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
