“…Given that in spray coating of solar cells and similar devices, the plate temperature is lower, the temperatures used by Sozbir et al [19] are rather high. However, the mist used in their experimentations resembles the spray generated by ultrasonic atomization, the emerging atomization technique for solar cell and similar devices.…”

Among few available methods, spray deposition, if understood and controlled well, is a viable candidate for the fabrication of quantum dot (QD) sensitized nanoparticle PV solar cells.Spray coating is a multi-process method comprising proces � es such as atomization of a multicomponent liquid, droplet dynamics and flight, droplet evaporation, droplet impact on the surface, spreading, drying and adhesion of the solid content to one another and to the substrate. In this paper, a model is proposed that may be used as a design and research tool for the spray coating of QD-sensitized nanoparticle thin film solar cells. The model may be used to study the effect of processing parameters on the thin film characteristics and quality and to predict the ideal distance between the nozzle and the substrate and other optimum design conditions .. Index Terms -thin film solar cells, photovoltaic cells, quantum dot sensitized nanoparticle solar cells, spray coating and deposition.

“…In recent years, water mist fire extinguishing technology has gradually replaced the Halon fire extinguishing agent as the most accepted fire extinguishing technology, 1 due to its high efficiency, low water consumption, and good pollution‐free effect. The nozzle is one of the core components of a water mist fire extinguishing system 2,3 .…”

The nozzle is the key component of water mist fire extinguishing system. As a response to the problems of small injection angle associated with straight jet nozzles and the weak axial momentum of swirl nozzles, a swirling–straight composite nozzle is designed in this work. The comparison with a straight jet nozzle and a pressure swirl nozzle shows that the swirling–straight composite nozzle has a larger axial momentum and better injection angle. Under the same pressure, the volume flow of the swirling–straight composite nozzle is more than 27% of the pressure swirl nozzle, and the injection angle was more than 65% of straight jet nozzle. The numerical model of the swirling–straight composite nozzle is established. Meantime, the internal flow field characteristics and the influence of the straight jet aperture on the performance are studied. The results demonstrate that the straight jet fluid and swirling fluid can be mixed well in the nozzle, and a larger axial momentum and tangential momentum can be obtained. With the increase of the straight jet aperture, the swirl effect in the nozzle becomes weaker, the injection angle becomes smaller, and the axial momentum improves. When the straight jet aperture increases from 1.1 to 1.9 mm, the straight jet volume flow at the nozzle inlet increases by 127%, and the injection angle reduces by 40%.
