摘要

The paper focuses on the numerical simulation of diesel oil droplet evaporation in a "stabilized cool flame" environment. For this purpose, a dedicated model is formulated, correlating cool flame induced heat release with local temperature and fuel concentration values. The developed model is capable of adequately describing the main physicochemical phenomena involved in the process and is deduced using both experimental data and chemical kinetic simulations. The model is implemented in an in-house developed two-phase CFD code and predictions are compared with available experimental data, achieving very good levels of agreement. Parametric studies examining the effects of temperature and fuel concentration variations on the thermal behaviour of the system are also conducted.
