“…To this end, engine research and development groups have been trying for decades to better understand and describe the fundamentals of these processes, including alternative fuels and combustion strategies [2] [3]. Both experimental and computational approaches have brought important insight towards enhancing our understanding of the global and local processes governing fuel mixing and combustion.…”

Elsevier Payri, R.; Viera Sotillo, JP.; Pei, Y.; Som, S. (2015). Experimental and numerical study of liftoff length and ignition delay of a two-component diesel surrogate. AbstractUnderstanding and controlling mixing and combustion processes is fundamental for the ever more demanding pollutant regulations and fuel consumption standards of direct injection diesel engines. The fundamentals of these processes haven been long studied from both experimental and numerical perspectives. As numerical models become more advanced, the need for adequate experimental data increases. Hence, experimental methodologies and scientific databases need to be enhanced with more quantitative, accurate, consistent, and reliable information in order to evaluate the models in a robust fashion. The present study seeks to enhance the current state-of-the-art by further evaluating the combustion performance of a two-

“…3a is the temperature field of spray flame of n-heptane (corresponding to D100, pure diesel) and iso-octane (corresponding to D0, pure gasoline). The co-flow temperature is 1055 K corresponding to test conditions in reference [2]. The temperature of the flame edge displayed is 1200 K. It can be seen that the lift-off height of nheptane spray is significantly lower than that of iso-octane under this temperature conditions.…”

“…The results were compared with experimental data in reference [2]. As the auto-ignition delay shifted too much in reference [2], it was transformed into logarithmic coordinates for convenience in Fig. 2a.…”

“…This indicates that the vaporization rate of iso-octane is faster than n-heptane. As is mentioned in reference [2] of this paper, the auto-ignition process was divided into two parts: the physical delay and the chemical delay. As for the physical delay, the density, viscosity and surface tension of iso-octane are smaller than those of n-heptane.…”

“…The concept of simultaneous auto-ignition temperature was proposed, when the temperature of CATA reaches TTTS, diesel and gasoline spray ignited spontaneously [2]. The reasons for the exists of T s under such experiment conditions were discussed and analyzed from the perspective of flame pattern, as well as the ignition delay and flame lift-off height of blend fuel spray.…”
