Experimental and numerical investigation on R744 ejector geometry.

Number: pap. ID: 383

Author(s) : BANASIAK K., HAFNER A., ANDRESEN T.

Summary

Experimental and theoretical investigation for the optimum ejector geometry was performed. Different ejector configurations were examined, for variable lengths and diameters of the mixing section and a variable angle of divergence for the diffuser. The 1D ejector model validation and a simplified geometry optimization based on computational results were performed. Based on both numerical simulation and experimental work, the ejector efficiency proved to be notably dependent on mixer length and diameter, as well as on diffuser divergence angle. The maximum level of the COP increment was registered at 8%, compared to the conventional system with an expansion valve.
