Comparative study of R744 ejector CFD models.

Number: 0380

Author(s) : RINGSTAD K., HAFNER A.


This work presents a comparative study of four different R744 ejector CFD models at a wide range of operating conditions. The models compared are the homogeneous equilibrium model, the UDRGM mixture model, a homogeneous relaxation model and a Eulerian two-fluid model. The results are also compared to experimental data available in the literature. The models are tested for high and low operating pressures, and the effects of non-equilibrium are discussed. The results are discussed and recommendations for model developments are suggested.
