This poses serious problems directly related to our understanding of the structure and scaling of wall-bounded flows. We take up one of such problems, namely, a re-examination of the velocity profile for the whole layer. We need such a type for the velocity profile that can describe the effect of the Reynolds number. And we here focus on the Reichardt-Finley composite velocity profile and show that it well represents the velocity profile of turbulent pipe flow. Indeed we can determine the constants kappa and B of the logarithmic profile from the velocity data by optimizing the profile fitting., 資料番号: AA0064237026, レポート番号: JAXA-SP-08-006}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {円管乱流の速度分布}, volume = {JAXA-SP-08-006}, year = {2009} }
