Much bigger discrepancies are shown by the SA model. It could be observed that the hot air is transported additional downstream than in experimental data, as well as the place in the total temperature maximum is closer for the internal annulus (multiperforated wall).

The differences exist in thezones in middle of of channel, in in centre from the vortex. The variations exist inside the zones close to internal and external end walls. They might result in the simplification on the close to internal and external finish walls. They may outcome in the simplification of your boundary situations at multi-perforated walls in the combustor simulator, as described boundary circumstances at multi-perforated walls within the combustor simulator, as pointed out above. An additional explanation for this distinction might be the confined test section configuration. above. A further explanation for this difference could be the confined test section configur.
