Flame–Flame Interactions and Jet–Jet Interactions in Gas Turbine Swirl Combustors
EnergiesAnnular combustors are widely used in newly developed aero-engines. Nevertheless, the development of annular combustors requires substantial air supplies and high-power heaters during testing, leading to high experimental costs.

Effect of Temperature Conditions on Flame Evolutions of Turbulent Jet Ignition
Energies, 2021 Turbulent jet ignition technology can significantly improve lean combustion stability and suppress engine knocking. However, the narrow jet channel between the pre-chamber and the main chamber leads to some difficulties in heat exchange, which ...

The Salinity of Coastal Waters as a Bellwether for Global Water Cycle Changes
Geophysical Research Letters, 2023 While the global water cycle has been studied previously based on land and open ocean studies, here we use coastal satellite sea surface salinity (SSS) data to show that in global aggregate, SSS variations near coasts are strongly correlated with global ...

Air/fuel mixing in jet flames [PDF]
Proceedings of the Combustion Institute, 2021 The paper examines eight diverse regimes in which fuels can mix and react with air. These comprise: (i) Lifted subsonic; and (ii) supersonic jet flames, with (iii) and without (iv) cross flows; (v) Rim-attached flames; (vi) Early Downwash flames; (vii) Downwash-attached jet flames; and (viii) Fire Whirls.

International Journal of Hydrogen Energy, 2013 A critical review and rethinking of hydrogen jet flame research is carried out. Froude number only based correlations are shown to be deficient for under-expanded jet fires. The novel dimensionless flame length correlation is developed accounting for effects of Froude, Reynolds, and Mach numbers. The correlation is validated for pressures 0.1–90.0 MPa,
