The eddy viscosity constant, εt, was set to a uniform value inside the turbulent part of the bubble. Overall characteristics of numerical results agreed closely with experimental results. The relation between εt and velocity distributions was analyzed by the momentum balance inside the bubble. It was shown that the pressure recovery inside the bubble is proportional to εt. Finally, εt is related to the non-dimensional parameter which represents the flow inside the bubble., 資料番号: NALTR1079000, レポート番号: NAL TR-1079}, title = {Analysis of Laminar Separation Bubbles Using a Simple Eddy-Viscosity Turbulence Modei}, year = {1990} }
