Ammonia, a carbon-free source of hydrogen has recently gained considerable attention as energy solution towards green future. Previous works have shown that adding 30VOL.% with ammonia can eradicate the drawbacks pure combustion but no study in literature investigated this blend across wide range equivalence ratios. The present work investigates 70/30VOL.% NH3/H2 from 0.55 ≤ Φ 1.4 for both premixed laminar spherically expanding flames and turbulent swirling at atmospheric conditions. A...
Ammonia appears a promising hydrogen-energy carrier as well carbon-free fuel. However, there remain limited studies for ammonia combustion especially under turbulent conditions. To that end, using the spherically expanding flame configuration, speeds of stoichiometric ammonia/air, ammonia/methane and ammonia/hydrogen were examined. The composition blends studied are currently being investigated gas turbine application evaluated at various intensities, covering different kinds regimes....
To achieve net zero carbon emissions, ammonia is gaining traction as a promising alternative fuel. However, the combustion characteristics of need further investigation. The current study aims to analyze laminar flame speed, fundamental physio-chemical property any combustible mixture, through experimental measurements and kinetic reaction mechanism analysis. speed 70/30 (%vol) NH3/H2 at atmospheric pressure ambient temperature across wide range equivalence ratios (0.6–1.4) was studied...
In this study, the natural convection of a hybrid nanofluid (TiO 2 –Cu–water) in square cavity with an elliptical heater positioned center is investigated numerically. Enhancing thermal systems requires understanding and heat transport. Heat efficiently transferred via nanofluids heat-emitting structures particular forms, such as ones. These elements are necessary to provide efficient transmission when constructing cooling nuclear reactors, computer processors, exchangers. The SIMPLE...
The combustion of ammonia requires, for most energy conversion systems, a promoter such as hydrogen to guarantee the start-up, stability and efficiency. Partially cracked (PCA) can provide sufficient concentrations enhance burning velocity in comparison with pure ammonia. However, little work exists on use PCA blends operating under relevant turbulent conditions. To that end outwardly propagating spherical flame configuration was employed determine laminar propagation characteristics...
As ammonia is a promising carbon-zero fuel, research focusing on its combustion properties has greatly increased. However, the interaction with key nitrogen chemistry species such as NO conditions remains poorly know. In order to improve fundamental understanding of NH3/NO interaction, series experiments and numerical simulations were carried NH3/NO/N2 mixtures. The spherical expanding flame method was employed measure laminar burning velocity Markstein length for different oxidizer mixtures...
