Gas turbine performance enhancement for naval ship propulsion using wave rotors

The propulsion demands of high-speed naval vessels often rely on gas turbines, producing significant amount power achieving thus high performance requirements. Gas turbines can be used either to provide purely mechanical propulsion, or alternatively generate electricity, which is subsequently by electric drives propel the ship. However, thermal efficiencies are lower than those Diesel engines similar power. In context improving existing marine it proposed enhance engine’s integrating a pressure wave supercharger (or rotor), while keeping basic components baseline engine unchanged. This article an application method developed author for with and without recuperator, [Fatsis 2019]. It found that important benefits obtained topped in comparison self-standing engines. rotor integration more appropriate low compression ratios turbine inlet temperatures. Application technology recuperated shows efficiency gain exceeding 19% all ratio temperatures examined.Abbreviations: COGAS, Combined steam turbine; COGES, steam; GTE,
