摘要

Abstract

In this paper

a dual-throat supersonic separation device with porous wall has been proposed to solve the starting problem of supersonic separator

and the feasibility of the proposed device has been tested numerically and experimentally. Its flow characteristics have been investigated and the effect of some important parameters including nozzle pressure ratio (R

)

inlet temperature and swirl intensity were examined. In the device

the supersonic flow state and strong centrifugal acceleration of 240000g can be obtained

which are necessary for the condensation and separation of water vapor. The supersonic region in the device enlarged and the shock wave shifted downstream along with the increasing R

. The separation performance was improved with the increasing R

and the inlet temperature. The best separation performance in this study was obtained with ΔT

=28 K.
