摘要：
This work deals with pre-vaporized n-heptane auto-ignition in turbulent flows. The paper applies the Eulerian Stochastic Field method to the solution of the sub-grid joint-scalar probability density function (PDF) of the reacting scalars in the Large Eddy Simulations (LES) context. A reduced mechanism of 22 species and 18 reactions is used to model n-heptane chemical kinetics. The method is able to reproduce the different regimes observed experimentally and studies the influence of inflow temperature fluctuations.
