A diffuser is disclosed that includes a splitter having a blunt forebody useful in re-starting a boundary layer. The blunt forebody can be used to create a static pressure bow wave and interaction with a passing fluid stream that reduces a thickness of boundary layer formed on an opposing wall. The re-start in boundary layer can be used in a way that allows an upstream portion of the diffuser to be sized approaching a separation limit and a downstream portion of the diffuser to also be sized approaching a separation limit. In some forms the passages spli...


1. An apparatus for a working fluid of a gas turbine engine, the apparatus comprising: a multi-passage diffuser disposed between a compressor and a combustor of a gas turbine engine, the multi-passage diffuser having: a first passage oriented to diffuse a first stream of working fluid traversing the first passage, anda splitter disposed at a downstream portion of the first passage to partition the first stream into a second passage having a second stream located radially outward of a third passage having a third stream,wherein a leading end of the splitt...
