Project Overview
High-end scientific computing methods are being applied to perform full-resolution numerical experiments, designed to explain the relationship between the fluid-, mixing-, and chemical-dynamics of split-injection. A novel modelling framework, built on the concept of fluid age is being developed; the age, or residence time, of a mixture is a natural reference quantity for understanding how kinetically limited combustion processes (e.g. autoignition, highly-dilute combustion, NOx and soot-particle formation) evolve. Subsequently the potential of this method for design of ultra-low-emission combustion systems will be demonstrated in automotive applications.
