✦ Synopsis

Experimental measurements of density and OH radical concentration have been compared with a theory which predicts the concentrations of product and of a reactive intermediate in a plane premixed flame propagating into grid turbulence. The theory is based on the simplest version of the Bray and Libby model extended to include the reactive intermediates. The results show excellent agreement for the density. For the OH the agreement is poorer although the theory does predict the correct trends, particularly the presence of superequilibrium concentrations. It is recommended that the most complete version of the Bray and Libby model be used for such flames with at least a two parameter fit for the reactive intermediate PDF.
