It is difficult to simulate both the flow field and the chemical reaction using, respectively, the flow state and kinetics calculations and actually reflect the influence of the gas flow state on the chemical change in a selective catalytic reduction SCR system. In this study, the flow field and the chemical reaction were therefore coupled to simulate a full Cu-Zeolite SCR system and the boundary conditions of the simulation were set by a relevant diesel engine bench test which included the exhaust temperature, the mass flow, and the exhaust pressure. Then, the influence of the gas flow state on the NO x conversion efficiency was investigated. This was used as guidelines to optimize the SCR system control strategy.

When volcanic gases enter the atmosphere, they encounter a drastically different chemical and physical environment, triggering a range of rapid processes including photochemistry, oxidation, and aerosol formation. These processes are critical to understanding the reactivity and evolution of volcanic emissions in the atmosphere yet are typically challenging to observe directly due to the nature of volcanic activity. Here, we foreground chemical kinetics in simulating this critical zone. Volcanic gases are injected into a chain-of-reactors model that simulates time-resolved high-temperature chemistry in the dispersing plume. Boundary conditions of decreasing temperature and increasing proportion of air interacting with volcanic gases are specified with time according to an offline plume dynamics model. In contrast to equilibrium calculations, our chemical kinetics model predicts that CO is only partially oxidized, consistent with observed CO in volcanic plumes downwind from source. The H 2 O 2 will likely augment volcanic sulfate yields by reacting with SO 2 aq in the cooled-condensed plume.

Развяжи, пока не явились агенты безопасности. - Они не придут, - сказала она безучастно. Хейл побледнел.
Когда он наконец заговорил, голос его звучал подчеркнуто ровно, хотя было очевидно, что это давалось ему нелегко. - Увы, - тихо сказал Стратмор, - оказалось, что директор в Южной Америке на встрече с президентом Колумбии. Поскольку, находясь там, он ничего не смог бы предпринять, у меня оставалось два варианта: попросить его прервать визит и вернуться в Вашингтон или попытаться разрешить эту ситуацию самому. Воцарилась тишина.
