Abstract

In this paper, the jet flow from an industrially relevant ultra-high-bypass-ratio (UHBPR) serrated nozzle has been simulated in a flight stream. The methodology to tackle complex geometries and multi-disciplinary physics is demonstrated in detail and validated using a single stream jet with measurements. A reliable industrial process chain is explored. This type of complex geometry jet simulation shows great potential to replace parts of experimental tests in the near future.
