Item Characterization And Commercialization Of The Counterflowing Nozzle(2016-12) Omidiannia, ZahraInterest in the atomization of liquids with different viscosities has been growing tremendously for decades because researchers understood how making an efficient aerosol can improve the efficiency of some applications such as combustion. The process of air-assisted atomization is done by mixing two phase flows, air and liquid. A new atomizer called a counterflowing nozzle was characterized in different conditions in which the low-density outer flow runs counter to the high-density core flow. In this project, both air and water were injected from upstream and mixed before orifice discharge to make a fine mist. Air as an external force is added to the fluid flow and disrupts its attenuated film; therefore, the surface energy increases. While experimenting, water and air flow rate and water and air pressure were changed and the efficiency of spray was observed until finding the optimal conditions. Also, different modes of the nozzle were found. The results of these experiments proved that the flow conditions observed in flow-blurring occurs independent of H/D; therefore, an efficient atomization regime similar to flow-blurring should be observed. Hence, it can create a finer mist compared to other jet-based atomizers. Finally, the marketing plan of the counterflowing nozzle was developed to explain the opportunities that this product has in the market and how it can succeed in industry.
