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

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.
