Thermodynamic analysis of gas turbine engines using wave rotor combustion

To investigate the performance of gas turbine engines using wave rotor combustion, one dimensional analysis of aerodynamical was performed and thermodynamical cycle model was established to verify the performance improvements and analyse the effects of parameter on the overall performance and eventually applied to an active service vortex rotor shaft engine. Results indicate that wave rotor combustion can significantly enhance the overall performance of gas turbines. The specific cycle work maximally increases by 39% and specific fuel consumption decreases by 28%, compared with the benchmark gas turbines. In view of design and optimization, the influence of loop parameters was taken into account. Improving the turbine inlet temperature can improve the performance of the engine. An optimal compressor pressure ratio exists. The higher the temperature of the turbine inlet, the greater the optimal compressor pressure ratio. Comparing and analyzing five different wave rotor-topping cases indicates keeping the compressor, turbine inlet temperature constant is a way to improve performance maximally.
