Energy efficient exhaust components for gas turbine engines for environmentally sound propulsion and power generation applications

加拿大在航空航天、船舶和工业应用的中小型燃气轮机发动机的设计和制造方面处于世界领先地位。加拿大还拥有世界知名的燃气轮机专用部件的售后行业，包括排气热交换器、专用排气喷嘴和喷射器，以及薄膜和喷雾冷却装置。*燃气轮机设计和开发是加拿大几十年来的一个主要研究领域。在内部空气动力学和燃烧领域的研究努力导致了非常高效的燃气轮机的发展。然而，缺乏对某些附加部件的重点研究，如专门的排气喷嘴和喷射器，导致了不必要的效率损失。这项研究计划将重点放在此类专门系统的设计和开发上的创新，以确保它们满足当今对高效率、低噪音和低排放的需求。**本研究建议侧重于燃气轮机专用排气部件的研究和创新。这项研究将特别着眼于排气系统，其中包括专门的混合喷嘴、超混合喷嘴、喷水蒸发冷却系统、空气-空气喷射器、热交换器、撞击冷却、气膜和渗流冷却。这项工作直接关系到加拿大安大略省渥太华的W.R.Davis Engineering Ltd等公司的利益，这些公司在加拿大为世界市场设计和制造这些部件。**

Canada is a world leader in the design and manufacture of small and medium sized gas turbine engines for aerospace, marine and industrial applications. Canada also has a world renowned after-market industry for specialized components for gas turbines including exhaust heat exchangers, specialized exhaust nozzles and ejectors, and film and effusion cooled devices. **Gas turbine design and development is, and has been a major area of research in Canada for decades. The research efforts in the areas of internal aerodynamics and combustion have lead to the development of very efficient gas turbines. However, the lack of focused research on certain add on components such as specialized exhaust nozzles and ejectors has resulted in unnecessary efficiency penalties. This research program will focus on innovation in the design and development of such specialized systems to ensure they meet today's demands for high efficiency and low noise and emissions. **This research proposal focuses on research and innovation for specialized exhaust components for gas turbines. The research will specifically look at exhaust systems that incorporate specialized mixing nozzles, hyper mixing nozzles, water spray evaporative cooling systems, air-air ejectors, heat exchangers, impingement cooling, film and effusion cooling. This work is of direct interest to Companies like W. R. Davis Engineering Ltd of Ottawa, Ontario, Canada who design and manufacture these components in Canada, for a world market. **
