A 1-D analysis of ejector performance
TL;DR: In this paper, a 1D analysis for the prediction of ejector performance at critical-mode operation is carried out, where constant pressure mixing is assumed to occur inside the constant-area section of the ejector and the entrained flow at choking condition is analyzed.
