Numerical simulation of premixed combustion combining level set with extended finite element methods

The G-function approach to premixed combustion problems is based on the flamelet concept. Thereby, the flame front is modeled as an embedded interface within the bulk. A level set function is used to describe the position of the flame front. To account for discontinuities in the velocity and the pressure fields across the interface, an eXtended Finite Element Method (XFEM) is applied. That is, the flow field, governed by the incompressible Navier Stokes equations, interacts with the G-equation in a coupled problem.     «
