Heating and Evaporation of Droplets of Multicomponent and Blended Fuels: A Review of Recent Modeling Approaches

In this review, recent models for the heating/evaporation of multicomponent and blended fuel droplets their implementation into numerical codes, used analysis processes in internal combustion engines, are reviewed. these models, diffusion species, recirculation, temperature gradient inside considered. The focus review is on group based analytical solutions to heat transfer species equations codes. Four key aspects summarized: (1) application Discrete Component (DC) model Multi-Dimensional Quasi-Discrete Model (MDQDM) a broad range fuels, including petrol, diesel, ethanol, biodiesel fuels blends, (2) formulation surrogates, with recently introduced Complex Fuel Surrogate (CFSM), (3) overview transient algorithm, Transient (TMDQDM), an autogeneration quasi-components, (4) latter computational fluid dynamics (CFD) code realistic engineering full cycle simulation engines. original modified versions DC MDQDM evaluated heating evaporation bio/fossil-fuel (e.g., ethanol/petrol/biodiesel/diesel) blends. These were implemented commercial CFD software validated. feasibility formulating complex surrogates engine before after onset (autoignition) described.
