A detailed numerical investigation of turbulent liquid jets in quiescent air is conducted, with the focus on the processes leading to liquid atomization. Spectral refinement of the interface is employed to provide an accurate description of the phase interface, even at the subcell level. The ghost fluid method is used to handle the different material properties of the phases and the surface ten...

Understanding the combustion characteristics of fuel droplets laden with energetic nanoparticles (NP) is pivotal for lowering ignition delay, reducing pollutant emissions and increasing the combustion efficiency in next generation combustors. In this study, first we elucidate the feedback coupling between two key interacting mechanisms, namely, secondary atomization and particle agglomeration; ...

We report tests of secondand third-generation density functionals, for pure density functional theory (DFT) and hybrid DFT, against the BH6 representative barrier height database and the AE6 representative atomization energy database, with augmented, polarized double and triple zeta basis sets. The pure DFT methods tested are G96LYP, BB95, PBE, mPWPW91, VSXC, HCTH, OLYP, and OPW91 and the hybri...

Liquid fuel injection and atomization have a significant influence on the combustion and emission characteristics of diesel engines. Using x-ray radiography, it is possible to obtain quantitative and time-resolved data in the primary breakup region close to the injector nozzle. However, most previous studies on model validations have employed optical measurements that are not applicable in this...

Use of biodiesel as an alternative to diesel could reduce the dependency on petroleum products and the pollution problem. The physical properties of the fuel such as viscosity, volatility and f lash point also affect the combustion process, thereby engine performance. Specif ically atomization of the fuel during the injection is attributed to higher viscosity of biodiesel. Injec ted fuel drople...
