ConclusionIn this a priori study based on experimental data we could illustrate how the special flow feature of this bluff-body stabilized flame (the mixing between fresh air and recirculated combustion products above the bluff body) makes invalid the assumptions usually made in presumed PDF modeling based on a mixture fraction and a progress variable in a RANS framework.
