25 Citations | Predicted results indicate that the partial closures may generate substantial local pressure peaks along the crack, implying a strong coupling between chamber pressurization, crack combustion, and propellant deformation, especially when cracks are narrow and chamber pressurization rates are high. |
In conclusion, the proposed model served as a robust tool to evaluate different parameters on the sealing capacity of the combustion chamber that contribute to minimizing global emissions. | |
47 Citations | The results showed that for complete sealing, the earlier the initial sealing time is, the better the fire can be suppressed with a shorter burning duration and lower temperature. |
75 Citations | The possible depression effect related to the fuel area of sealing on combustion was observed in the experiment. |
13 Citations | Moreover, the sealing interference, among several other factors, greatly affects the life of the sealing ring. |
12 Citations | Our results indicate significant differences in sealing integrity due to chamber-collar sealing strategy. |
74 Citations | Results of the analyses show that combustion instabilities occur in all the experimental operating conditions. |
32 Citations | It was found that heat transfer has an important effect on the combustion dynamics when the flame interacts with the sidewalls of the chamber. |
91 Citations | Numerical analysis reveals that the differences in flame blowout limits are a result of the combined effects of heat recirculation and local flow field at the entrance of the combustion chamber. |

What are the problem of ammonia combustion?5 answersAmmonia combustion faces several challenges. These include issues such as low flame speed, high ignition temperature, and the generation of undesirable emissions like NOx and N2O. The slow burning rate of ammonia contributes to the increased production of NOx and N2O, further complicating the combustion process. Additionally, the large latent heat of evaporation in liquid ammonia leads to a strong cooling effect, negatively impacting flame stabilization and combustion efficiency. Experimental and numerical studies have shown that the concentration of exhaust emissions like NO and N2O increases with higher Reynolds numbers, affecting flame characteristics and emission levels. These challenges necessitate a deeper understanding of ammonia combustion dynamics to optimize combustion efficiency and reduce emissions in practical applications.
What are the health problems caused by diesel exhaust?5 answersExposure to diesel exhaust can cause a range of health problems. Acute exposure to diesel exhaust can lead to irritation of the eyes, nose, throat, and respiratory tract. Diesel exhaust has been categorized as a likely human carcinogen based on findings in experimental animals and humans. In terms of respiratory effects, inhaled diesel particulate emitted by vehicles can impair respiratory mechanics, reduce inspiratory capacity and static compliance, and increase Newtonian resistance. Diesel exhaust exposure has negative impacts on the lungs, heart, and brain, and individuals with pre-existing respiratory conditions may be more susceptible to these effects. Additionally, diesel exhaust is associated with a variety of occupational diseases, including respiratory and lung diseases. Furthermore, exposure to diesel exhaust particles can cause neurotoxic responses, oxidative damage, inflammation, and microglial activation in the brain.
