The Research on Characteristics of a New Type of Marine Gas Turbine Exhaust Ejector Device

Abstract:

Marine gas turbine exhaust ejector device is responsible for reducing or eliminating the infrared signatures of exhaust system. In order to optimize the structure of exhaust ejector and shorten the cycle of research, it is essential to study the successful experiences on exhaust ejectors by scholars abroad. In this article two structure innovations were introduced: the nozzle structure changing from circular to rectangular and multi-stage diffuser, then a new type of marine gas turbine exhaust ejector was designed. Through simplifying the ejector model, numerical simulation was used to predict the characteristics of both the single-stage ejector and the multi-stage ejector. The result indicates the effects of structural parameters on the performance parameters. This research result has certain reference value for marine gas turbine exhaust ejector structure innovations and performance optimization.
