Chapter 10.0 APPENDIX D Superposition of Loss Terms This derivation evolved in the exploration of superposing individual loss mechanisms. Because loss is a method for quantifying entropy generation, each loss mechanism correspondingly generates entropy. If these mechanisms behaved linearly, then superposition of entropy would result in the total entropy and therefore the total loss. The author knows of no investigator who currently employs this method of calculating total loss. It is common, however, for simulations to sum individual loss calculations. The derivation below demonstrates the difference between these two methods of calculating total loss. For simplicity, it is shown for a 2-D linear cascade. However, a similar result can be demonstrated for a 3-D annular cascade. Method 1: Total Loss Calculation using Superposition of Entropy From the definition of loss, ωT =(Pt1 -Pt2)/(Pt1 -P1) ωT = ( 1 - Pt2/Pt1) / ( 1 - P1/Pt1) Assuming a perfect gas with no work or heat transfer along streamline, Pt2/Pt1 =e-∆ST /R ∴ω In order to further simplify the analysis, assume that the only two mechanisms that contribute to loss are shocks and boundary layers. Superposing the entropy generated from each mechanism we obtain ∆ST = ∆SSH + ∆SPR =(1-e-∆ST /R)/(1-P /P ) T 1 t1 ω =(1-e-(∆SSH +∆SPR)/R)/(1-P /P ) T 1 t1 ω =(1- e-∆SSH/R *e-∆SPR /R ) / (1-P /P ) T 1 t1 (10.1) 79PDF Image | Gas Turbine Design Axial Flow Compressors

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
