paraphrase

Standards 1. Rephrase - Use as few words as possible from the original text 2. Not change the meaning 3. Cite the paraphrase Without proper citation, your paraphrase could be construed as plagiarism When should you reference? You need to reference every time you use another person’s work or ideas. This includes: • Quotes: Using the words exactly as they appear. You must enclose the words in quotation marks “ ”. • Paraphrases: Using the idea(s) but in different words. This means more than changing one or two words. • Summaries: Expressing the main points in your own words. When you paraphrase, your task is to distill the source's ideas in your own words. It's not enough to change a few words here and there and leave the rest; instead, you must completely restate the ideas in the passage in your own words. If your own language is too close to the original, then you are plagiarizing, even if you do provide a citation. In order to make sure that you are using your own words...

airfoil polar data extrapolation

‎ Table of Contents 1. aifoil polar extrapolation 1.1. Reference 1 aifoil polar extrapolation NACA0012 cl cd data 1 naca0018 polar data 2 method 1 extrapolation can be done using Javafoil, or NREL's AirfoilPrep 3 based on Viternas method 4 Method 2 extrapolate cl, cd up to the stall delay angle using the method proposed by Snel et al. 5 . Further extrapolations beyond the stall delay angle were achieved using Viterna and Corrigan’s methodology for post stall predictions 6 . empirical correction used by batten 2008, University of Southampton Airfoil polars measured in the wind tunnel or simulated with XFOIL or other CFD software are usually limited to small and medium inflow angles (e.g. -20° to +20° AoA). However the blades of both VAWTs and HAWTs often operate at high inflow angles. In order for the BEM routines to converge and produce rea...
