There is renewed interest in hydrogen as an alternative fuel for aero engines, due to their perceived environmental and performance benefits compared jet fuel. This paper presents a cycle, thermal performance, energy creep life assessment of with fuel, using turbofan engine. The cycle was simulated code developed by the authors that allows be selected input. exergy uses both conservations mass ...

We present a methodology for the computation of flow fields involving complex perforated surfaces in propulsion applications. Of particular interest is the treatment of perforated flaps used as wedge-shaped fan flow deflectors for reducing jet noise of a supersonic turbofan engine. A three-dimensional Reynolds-Averaged Navier-Stokes solver is used to compute the flow field of the external jet p...
