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 partiallypremixed and premixed turbulent combustion turned out to be a very challenging task. A promising way to extend the range of applicability of PDF methods to the fast flamelet chemistry of turbulent premixed flames is described here. Simulation results of three turbulent premixed flames demonstrate the suitability of this approach. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
