Computational modeling of two-phase ejector flow

Abstract EN

IIn this study, a CFD code based on a parabolic two-fluid model is introduced to simulate two-phase flow in refrigerant ejectors.

The CFD results were validated with the experimental results of some different authors.

After the validation is satisfied, this paper is able to predict the flow phenomena inside the ejector when its operating conditions were varied.

The code was used as a design tool to improve ejector performance in the ejector expansion refrigeration cycle service.

The CFD method was evaluated as an efficient tool to represent the flow inside ejectors.
