FPVCentralFoam-3.0.1

Description

This code realizes a steady laminar flamelet approach for turbulent non-premixed combustion. The solver is based on ''rhoCentralFoam'', i.e. it is density-based (For high speed flow, Mach > 1), compressible and runs with both LES and RAS turbulence.

The theory is mainly taken from the work of N. Peters and is based on the view of a turbulent flame as an ensemble of laminar flamelets. The calculation of these flamelets is a one-dimensional problem and can be done in a pre-processing step. Integration using a presumed beta-Probability Density Function (PDF) accounts for the interaction between turbulent fluctuations and chemistry. The results of the pre-processing procedure are stored in tables which are accessed during the simulation. Values of interest, such as species mass fraction or enthalpy, are looked-up and connected to the flow using three parameters - the mixture fraction, its variance and the progress parameter. In doing so, the expensive solution of chemical mechanisms during run-time can be avoided and the run-time thus reduces significantly.
