Ammonia marine engine design for enhanced efficiency and reduced greenhouse gas emissions
Nature CommunicationsPilot-diesel-ignition ammonia combustion engines have attracted widespread attentions from the maritime sector, but there are still bottleneck problems such as high unburned NH3 and N2O emissions as well as low thermal efficiency that need to be solved ...

The scaling of model test results to predict intake hot gas reingestion for STOVL aircraft with augmented vectored thrust engines [PDF]
The difficulties of modeling the complex recirculating flow fields produced by multiple jet STOVL aircraft close to the ground have led to extensive use of experimental model tests to predict intake Hot Gas Reingestion (HGR).

Turbulence, combustion, pollutant, and stability characterization of a premixed, step combustor [PDF]
A two dimensional combustion tunnel was constructed to study a lean premixed turbulent propane/air flame stablized behind a rearward facing step. Studied were: (1) the existence and importance of large coherent structures in turbulent reacting and ...
