  • Mixing in Outer Swirling Coaxial Jets

    2019-9-1 · In this study, the developing region of coaxial jets is investigated numerically by varying the swirl for a fixed velocity ratio. Obtained results show that the mean flow properties and fluctuating concentration of the jet fluids except for the swirl velocity and helicity remain unaffected for the change in swirl ratio. Further, the helicity profiles indicate that the spiral motion due to ...

    2008-9-18 · Studies show that filtration is a good method to prevent outside pathogens from penetrating the building envelope through the mechanical ventilation. Kowalski and Bahnfleth , showed that 80- and 90-per-cent filters can produce air quality improvements that approach those achieved with HEPA filters, but at much lower cost. Another finding is ...

    2020-12-16 · High field-effect mobility can be achieved by oxidizing the TFTs, but the metal-oxide materials have intrinsic poor mechanical properties in wearable applications. For OTFTs of organic inks deposited on metal electrodes, the material interfaces normally show poor electrical contact with each layer on flexible substrates.
