Multidimensional Numerical Simulation of the Reacting Flow in a Pulse Combustor

چکیده
We have developed a new modeling capability to study the behavior of pulse combustors. Our approach is based on the use of higher-order Godunov methods combined with adaptive strategies to focus computational eeort where it is required and a Cartesian grid formulation for modeling realistic engineering geome-tries. The model computes quasi-one-dimensional, axisymmetric, and fully three-dimensional, reacting uid dynamics in the combustion chamber and incorporates lower-dimensional approximations for both the inlet valve that controls the injection of fuel and the tail pipe whose acoustic properties drive the combustion oscillations.

LES/FMDF of premixed methane/air flow in a backward-facing step combustor
In the present study, a hybrid Eulerian-Lagrangian methodology is utilized for large eddy simulation (LES) of premixed fuel/air flow over a three-dimensional backward facing step (BFS). The fluid dynamic features are obtained by solving the Eulerian filtered compressible transport equations while the species are predicted by using the filtered mass density function method (FMDF). Some scalar f...
