Aerodynamics of Marine Gas Turbine Inlet and Exhaust Systems

Abstract

Inlet and exhaust components represent the major part of the overall gas turbine installation and can, if not correctly designed, impose severe performance penalties and risk of mechanical failure. Due to early problems, considerable research has been undertaken over the past years to understand the mechanism of complex flows in ducts of constrained shape and size to enable a “Design Code of Practice” to be established. The work has been undertaken at UK Research Establishments, and Universities, by the Ministry of Defence, Royal Navy, which has resulted in revised types of installatons in which weight, space, and costs have all been substantially reduced.
