Experimental Study on the Infrared Signature Suppression Device of a Marine Gas Turbine Exhaust System

Abstract

Abstract: An experiment was carried out to study the ejector. The impact of the distance of the nozzle and the mixer was tested. Different nozzles were also used. The temperature field on the outlet baseline of the ejector was recorded as well as the static pressure of the main stream. The results indicate that the exhaust temperature is reduced most effectively when the distance ratio a/D reaches 0.875. In addition, decreasing the outlet area of nozzle helps to lower the exhaust temperature but will also increase the resistance of the infrared suppressor.

Key words: infrared suppressor, lobed nozzle, mixer, diffuser, pumping
