Numerical Investigation of Heat Transfer in a CO2 Two-Phase Ejector [PDF]
Energy, 2018 Abstract In this paper, the influence of heat transfer in the walls of an R744 two-phase ejector on ejector performance was investigated. A numerical investigation was performed using a computational fluid dynamic (CFD) model of the R744 two-phase flow coupled with the heat transfer inside the ejector.
