Konstantinos G. Kyprianidis Module Development 3.1.3.2 Component modelling A brief description of the modelling carried out for each engine component is presented in this section. Only the features relevant to the engine configurations studied in this thesis are described. Some of the component characteristics used with the newly developed performance code are presented in Appendix C. The thermo-fluid model used is discussed in detail in Chapter 4. The atmosphere component is used for calculating the ambient pressure and temperature for the given altitude and temperature difference from ISA (International Standard Atmosphere) conditions according to [96]. The intake component is used for calculating the free stream total conditions and momentum drag for a given value of flight Mach number and inlet mass flow. The outlet total pressure is then calculated assuming a certain level of pressure losses as a function of the flight Mach number [88]. In the fan component, separate characteristics are used for the fan root and fan tip. The calculations do not account for Reynolds number effects. However, the movement of the dividing streamline at deviating off-design bypass ratios is ac- counted for using the methodology described in [71]. Compressor characteristics are also used for the Intermediate Pressure Compressor (IPC) and High Pressure Compressor (HPC) components. The pressure drop in the various duct components is expressed as a fraction of the component’s inlet total pressure. The recirculating flow used for the fan disc pressurised sealing is simulated as a constant fraction of the IPC inlet mass flow. The IPC handling bleed flow is mixed with the main flow in the bypass duct component. This handling bleed is only required for the flight and ground idle operating points, as well as for approach. The required customer bleed flow may be extracted either from the IPC or the HPC component. The actual amount extracted varies with flight altitude. The intercooler component is positioned between the IPC and the HPC. Inter- cooler effectiveness can be calculated at off-design using either the correlation presented in [88] or a scaled component characteristic; either temperature effec- tiveness or the standard textbook thermodynamic definition may be used. The pressure drop in the intercooler is specified as a fraction of the total pressure at the inlet of each stream, hot and cold. Both “hot” and “cold” pressure losses are 41PDF Image | Multi-disciplinary conceptual design of future jet engine systems

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
