RESUMO
The use of probability density function (PDF) methods for turbulent combustion simulations is very attractive because arbitrary finite-rate chemistry can be exactly taken into account. However, many real flames involve a variety of mixing regimes ( non-premixed, partially-premixed and premixed turbulent combustion), and the development of PDF methods for partially-premixed and premixed turbulent combustion turned out to be a very challenging task. The extension of the range of applicability of PDF methods to the fast flamelet chemistry of turbulent premixed flames is shown in this work. It is worth noting that the same methodology can be used in corresponding filter density function (FDF) methods.
