Developing Numerical Models for the Combustion and Soot Formation of Alternative Fuels

随着交通运输业的不断扩张以及对环境和气候变化的担忧不断加剧，燃烧产生的烟尘（黑碳颗粒）和二氧化碳越来越受到人们的关注。烟尘排放已被确定对北极融化有重大影响；大气中的小烟灰颗粒吸收阳光并温暖空气，而较大的颗粒最终落到地面，其较深的颜色加速了冰雪的融化。因此，开发减少烟尘颗粒形成和排放的技术仍然是研究人员的重要目标。二氧化碳排放也是全球气候变化的一个主要问题。二氧化碳是燃烧的必要副产品，但通过使用替代燃料有可能减少其排放。例如，从植物中提取的生物燃料排放的净二氧化碳较少，因为它们在生长过程中吸收和处理二氧化碳。

As the transportation industry continues to expand and concerns over the environment and climate change continue to rise, combustion-generated soot (black carbon particulate) and carbon dioxide are growing concerns. Soot emissions have been identified as significantly contributing to Arctic thawing; small soot particles in the atmosphere absorb sunlight and warm the air, while larger particles eventually fall to the ground, where their darker colour speeds the melting of snow and ice. Thus, the development of techniques to reduce soot particle formation and emissions remains an important goal of researchers. Carbon dioxide emissions are also a major concern when it comes to global climate change. Carbon dioxide is a necessary by-product of combustion but its emissions have the potential to be reduced through the use of alternative fuels. Biofuels, for example, that are derived from plant matter emit less net carbon dioxide since they absorb and process it while they grow.
