configuration of a high-speed small-size centrifugal impeller. The influence of different SRCT
configurations on the impeller flow field at near-stall condition has been analyzed, highlighting
the improvement in stall flow ability. This paper also discusses the influence of the SRCT
configurations on the inlet flow angle, inlet swirl velocity and loss distribution in the impeller
passage to understand the mechanism of the SRCT configurations in enhancing the stall margin of
the impeller. The variation of the bleed flow rate at different operating conditions is also
presented in this paper. Finally, the time-averaged unsteady simulation results at near-stall point
are presented and compared with steady-state solutions. Copyright © 2012 by ASME.

Abstract: The objective of this work is to understand the surface/interface effect and the
size/configuration dependence on the mechanical properties in nanoporous membrane. The
stress concentration, nanopores coalescence, effective elastic moduli, damage level, and
contraction or expansion areas are numerically investigated in membrane where three
