ABSTRACT:
The invention relates to a method and apparatus for improving the performance of back-to-back turbocompressor or turbopump systems, or, more generally, of internal-separation energy separators. A helicoidal or spiral baffle is used to impart simultaneously a positive prerotation to the flow which is to be de-energized and a negative prerotation to the flow which is to be energized.
