| description | Numerical computations are carried out using an engineering-level Large Eddy Simulation
(LES) model that is provided by a commercial CFD code CONVERGE. The analytical framework
and experimental setup consist of a single cylinder engine with Transparent Combustion
Chamber (TCC) under motored conditions. A rigorous working procedure for comparing and
analyzing the results from simulation and high speed Particle Image Velocimetry (PIV)
experiments is documented in this work. The following aspects of LES are analyzed using
this procedure:
number of cycles required for convergence with adequate accuracy;
effect of mesh size, time step, sub-grid-scale (SGS) turbulence models and
boundary condition treatments;
application of the proper orthogonal decomposition (POD) technique. |
