For the purpose of simulation and obtaining a non uniform boundary condition, the total pressure and velocity sampled points at the outlet plane (Aerodynamic Interface Plane) were extracted and transformed into polar coordinates using the following transformation: Yc = Ymax + Ymin 2 Zc = Zmax + Zmin 2 R = (Y − Yc)2 + (Z − Zc)2 Z−Z R = arctan c Y −Yc their (7.1) (7.2) (7.3) (7.4) For the computation of equation 7.4, the ’atan2’ function in python is used so that the angular coor- dinate over the entire 360◦ sector is taken into account. After transforming the coordinates, both the total pressure and velocity values were then sampled along specified radius. Subsequently, the plot of total pressure and velocity against the circumferential position for each radial position are produced and compared. This is illustrated in figure 7.7, 7.8 and 7.9. As seen in figure 7.8, the total pressure distortion is greatest closest to the tip radius. This is primar- ily due to the fact that fuselage boundary layer accumulates primarily at region close to the bottom segment of the outlet plane, leading to a greater pressure drop. Secondly, the greatest pressure drop 75PDF Image | Aerodynamic Design of the NASA Rotor 67 for Non Uniform Inflow

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
