Abstract

Internal combustion in transport vehicles is still one of the biggest contributors to ultrafine particle emissions which have been proven to have many adverse effects on human health and the environment in general. To mitigate this problem a variety of particle filters have been developed and along with these filters a whole range of models aiming to optimise filter performance. This paper reviews a wide variety of particulate filter models for vehicular emission control and presents the volume of work in a unified and consistent notation. Particle filtration models are examined with respect to their filtration efficiency, the way they handle particle deposits within the filter wall, the formation of filter cake and the role of catalytic conversion and the effect of gaseous emission. Further, the impact of the chemical and physical properties of particulate deposits on the filter regeneration process is analysed and reaction pathways and rates are presented. In addition the accumulation of ash deposits and its impact on the filter behaviour is critically reviewed. Finally, various measures are identified that can potentially improve the current particle filter models.

模拟处理沉积物微粒过滤器的内燃排放

运输车辆的内燃仍然是超细颗粒排放的最大来源之一，超细颗粒已被证明对人类健康和环境有许多不利影响。为了缓解这个问题，已经开发了各种粒子过滤器，并与这些过滤器一起开发了一系列旨在优化过滤器性能的模型。本文综述了各种用于车辆排放控制的颗粒过滤器模型，并以统一和一致的符号介绍了工作量。对颗粒过滤模型的过滤效率、处理过滤壁内颗粒沉积的方式、滤饼的形成以及催化转化的作用和气体排放的影响进行了研究。此外，还分析了颗粒沉积物的化学和物理性质对过滤器再生过程的影响，并给出了反应途径和速率。此外，还对灰沉积物的积累及其对过滤器性能的影响进行了严格的审查。最后，确定了各种可能改进当前粒子滤波模型的措施。

期刊介绍： Progress in Energy and Combustion Science (PECS) publishes review articles covering all aspects of energy and combustion science. These articles offer a comprehensive, in-depth overview, evaluation, and discussion of specific topics. Given the importance of climate change and energy conservation, efficient combustion of fossil fuels and the development of sustainable energy systems are emphasized. Environmental protection requires limiting pollutants, including greenhouse gases, emitted from combustion and other energy-intensive systems. Additionally, combustion plays a vital role in process technology and materials science. PECS features articles authored by internationally recognized experts in combustion, flames, fuel science and technology, and sustainable energy solutions. Each volume includes specially commissioned review articles providing orderly and concise surveys and scientific discussions on various aspects of combustion and energy. While not overly lengthy, these articles allow authors to thoroughly and comprehensively explore their subjects. They serve as valuable resources for researchers seeking knowledge beyond their own fields and for students and engineers in government and industrial research seeking comprehensive reviews and practical solutions.
