The atomization process is critical for combustion systems since it directly influences emissions and performance. Thus injection system should provide the spray required structure characteristics, e.g., angle droplet size distribution. Therefore, this work investigates effects of varying fuel type, air co-flow rates, mass flow rate temperature on characteristics (e.g., distribution velocity) i...

Abstract Since perfluorohexanone can play a role in cooling and extinguishing the heat loss of lithium batteries, it is urgent to study atomization characteristics different ambient pressures (49 kPa, 75 101 kPa) ensure flight safety all-electric aircraft future storage use lithium-ion battery high plateau areas. The process primary secondary breakup was studied by using VOF-DPM model, influenc...

The use of microflow reactors enabled dramatic improvements in the apparent rates photochemical reactions. However, scaling-up photomicroreactors remains a challenge due to difficulties distributing light and flow all units photomicroreactors. In this work, mass photon transfer limitations an easily scalable micro-structured reactor, aerosol photoreactor, was studied. reactor concept, each drop...

It is important to study the characteristics of nozzle deluge spray comply with standards developed by petroleum industry for offshore installations in Norway. Due stochastic nature decomposition processes and geometrical features within nozzle, has a complex flow field. Since field determines performance spray, present performs an experimental characterization medium velocity validation comput...

In many combustion and agricultural applications atomizers are used to increase the surface area of liquid ensure high rates mixing improve evaporation. The most common, simple, reliable atomizer is pressure swirl atomizer. This said have quality effective atomization compared others induces swirling motion gives a hollow cone spray with air core as it emerges from exit orifice. To enhance unde...

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...

required for setting up the stiffness matrix. The far-field part of the matrix can be approximated by compression schemes like the fast multipole method or H-matrix techniques. The near-field part is typically approximated by special quadrature rules like the Sauter-Schwab technique that can handle the singular integrals appearing in the diagonal and near-diagonal matrix elements. Since computi...
