An improved spark ignition model for LES

The presentation demonstrates the modeling capabilities of the newly implemented ISSIM-LES ignition model to correctly capture early flame variability in a production high performance engine. Results are compared to more traditional models.

Experimental validation of DES model for a wing

The flow around a wing is usually well represented by a RANS simulation in cruise conditions, when no zones of separated flow are present. On the contrary, as the angle of attack increases because of the request of higher lift values, the flow separations become important, and the flow is more complex.
