主讲内容：Accurate and robust two-phase flow, spray and combustion models, ensuring grid-convergent results, can facilitate predictive simulations of fuel air-mixing and subsequent combustion process in internal combustion engine and advanced propulsion systems. The first part of the talk provides an overview of novel spray Eulerian models, including sub-critical and supercritical regimes with real fluid thermodynamics. Results are compared against accurate experimental data, like x-ray radiography and interfacial area data. In a second part, some recent simulations of spark ignition engine combustion will also be presented, relating the effects of standard and advanced ignition systems with the engine stability behavior in lean conditions. The seminar will conclude with a discussion concerning the challenges with respect to further developing the two-phase and combustion models.
