This work aims at providing novel insights into the entrainment
and energy exchange phenomena within a supersonic ejector.
To this end, advanced analysis tools based on momentum
and energy tubes (Meyers and Meneveau ) are extended to the
compressible nature of the flow and applied to the transport and
mixing phenomena within the ejector. New indicators of mixing
are introduced in order to investigate quantitatively transfer between
the primary and the secondary streams all along the ejector.
It is shown that there is no analogy between the transfer of
momentum and the gain in exergy of the secondary stream.
Papers presented to the 12th International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics, Costa de Sol, Spain on 11-13 July 2016.
