R744 multi ejector development.

Summary

The ejector design is defined by the operational conditions and by the system/application the ejector will be used for. By changing the geometrical design of the ejector, the characteristics of the ejector will change and the operational area where the ejector is more efficient will also change. Different system designs will have different requirements and will require/benefit most from ejector designs that are adapted to the unique characteristics of each system type. The present paper is briefly describing an investigation of typical ejector systems along with the characteristics of an ejector dedicated for these systems. Experimental studies were conducted by SINTEF with a multi ejector and different geometrical ejector designs where investigated. Almost 1000 experiments have been performed mapping the various ejectors at different operational conditions.
