Abstract
The importance of transient process in channels flows applying to aerospace engines engineering is discussed. The simple engineering approach for hydraulic resistance by turbulent flow estimation presented. A common analytical decision for Prandtl type equation for resistance coefficient carried out. The results of modern approach for turbulent flow in round cannel calculation presented.Keywords:
