Waste Heat Recovery from Gas Turbine Engine and Centrifugal Compressor Volute Design Optimization
Abstract
As the nation's top user of energy, the U.S. Department of Defense (DOD) has initiated ways to become more energy efficient. The Naval Postgraduate School contributes to this initiative by studying the possibilities of waste heat recovery from the exhaust stream of an Allison T63-A-700 gas turbine engine. Previous work centered on the design of two heat exchangers integrated into the exhaust duct work and using carbon dioxide as a working fluid. In support of this present work, modifications were made to the carbon dioxide flow path through the heat exchanger as well as the data acquisition system in order to provide further analyses of the heat exchanger's effectiveness. Baseline data measured in previous work on one of the heat exchangers was confirmed for this research, in addition to establishing new baseline data of the second heat exchanger. Additionally, this thesis expanded on previous computational fluid dynamics analysis of a centrifugal compressor and volute, studying the effects of compressor performance with varying rotational velocities and back pressures.
