Description:
|
The level set approach is used for fully
compressible simulations of premixed combustion. The motivation of the present work is
to numerically simulate thermo-acoustic combustion instabilities. These instabilities
are excited by the interaction of heat release and pressure fluctuations, which can
numerically only be accurately accounted for in fully compressible simulations. A major
challenge is the discretization and the inclusion of the heat release due to combustion
at the flame front. To this end, a finite-volume formulation, which uses the ideas of
the ghost-fluid method [Fedkiw et al. J. Comp. Phys. 154, 393-427 (1999)], is developed
based on a low-dissipation scheme which has been successfully used for large-eddy
simulations of non-reacting flows. |
