compressed air mixture 52 results in an intermediate compressed air pressure and temperature exiting the suction chamber 42 the intermediate compressed air 52 enters mixing tube 54 and passes through the diffuser 56 before delivery to the second target port 30 of turbine 14 through discharge outlet 58 the increased surface area for interlayer drag between the high and low pressure compressed air 26 18 flowing through the suction chamber 42 results in the entrainment ratio the quantity of low pressure air taken up by the motive force of the high pressure air being increased and over a broader range of operational conditions with an improvement in the entrainment of lower pressure air the efficiency of the turbine system can be increased computational fluid dynamics cfd models have been created to evaluate ejector performance with different nozzle structures as shown in fig4 one example of an application of the multi nozzle ejector system of the present invention results in an improved entrainment ratio over single nozzle ejectors in the same application with the overall efficiency defined as the integral of weighted entrainment ratio over the ambient temperature range a five percent gain in overall efficiency is shown with the multi nozzle design illustrated in fig4 this example is intended to show the performance improvement of the multi nozzle ejector.
