Figure 13. Surface temperature distribution and excitation voltage of AC-DBD of multi-actuator model for deicing test. equation 3, where L denotes the span length of the actuator. The actuators with different lengths and trips are tested. The averaged active power per unit length, PU.L, for all different lengths and trips actuators at different voltages is presented in Fig. 15. It shows the active powers for de-icing and anti-icing test using plasma actuation are almost the same and nearly as the function of the active voltage. 1􏰎 PU.L = nT.L V (t).I(t)dt (3) nT a) Deicing test. b) Anti-icing test. Figure 14. Power consumptions at different voltages for different test cases in unit span length for de- and anti-icing test. The power density per unit area, PU.S, for anti-icing test is shown in Fig. 16, which is calculated using equation 4, where S denotes the area wrapped by plasma actuators. It shows that it is proportional to the voltages in our experimental condition. In anti-icing wind tunnel test, it was shown that the surface temperature becomes higher than 0 ◦C at 12.0 kV for multi-actuator model, at which voltage, the power density is 13 kW/m2 per unit area. 11 of 14 American Institute of Aeronautics and Astronautics Downloaded by NORTHWESTERN POLYTECHICAL UNIV. on June 23, 2016 | http://arc.aiaa.org | DOI: 10.2514/6.2016-4019

Infinity Supercritical CO2 10 Liter Extractor Design and Worldwide Rights: The Infinity Supercritical 10L CO2 extractor is for botanical oil extraction, which is rich in terpenes and can produce shelf ready full spectrum oil. With over 5 years of development, this industry leader mature extractor machine has been sold since 2015 and is part of many profitable businesses. The process can also be used for electrowinning, e-waste recycling, and lithium battery recycling, gold mining electronic wastes, precious metals. CO2 can also be used in a reverse fuel cell with nafion to make a gas-to-liquids fuel, such as methanol, ethanol and butanol or ethylene. Supercritical CO2 has also been used for treating nafion to make it more effective catalyst. This NFT is for the purchase of worldwide rights which includes the design. More Info
