Direct numerical simulation of a spatially developing n-dodecane jet flame under Spray A thermochemical conditions: Flame structure and stabilisation mechanism

We present results from a three-dimensional (3D) direct numerical simulation (DNS) of a spatially developing n-dodecane round jet flame. The thermochemical conditions (i.e. pressure, temperature and oxidiser composition) correspond to those of Spray A, an experimental target flame of the Engine Combustion Network (ECN). To make the DNS computationally tractable, we consider a gas jet with a reduced Reynolds number of 17,000 and a shorter lifted...
