Download or read book Strategies to reduce friction losses and their implications for the energy efficient design of internal flow domains written by Daschiel, Gertraud Maria and published by KIT Scientific Publishing. This book was released on 2015-01-29 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work aims at developing a strategy how the energy which has to be applied to transport incompressible and Newtonian fluids through straight ducts can be reduced. Based on the physical properties of laminar and turbulent flow, models are derived which theoretically lead to the reduction of the dissipated energy. The possibility to implement the proposed state due to appropriate design aspects in the cross section shape of the duct is investigated based on numerical simulations of the flow.

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.
