Download or read book High accuracy determination of skin friction differences in an air channel flow based on pressure drop measurements written by Güttler, Andreas and published by KIT Scientific Publishing. This book was released on 2017-04-13 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present work delivers a versatile, accurate and reliable wind tunnel facility that is particularly developed to test different flow control techniques for drag reduction in precisely adjustable test conditions. Skin friction changes of 0.4% are resolved, which is comparable to the most accurate reported studies in liquids. this high accuracy is verified through a comprehensive uncertainty analysis. Subsequently, various passive and active flow control strategies are investigated.
