RISA New Model for Free-Stream Turbulence Effects on Boundary Layers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A model has been developed to incorporate more of the physics of free-stream turbulence effects into boundary layer calculations. The transport in the boundary layer is modeled using three ...
An Application of Octant Analysis to Turbulent and Transitional Flow Data
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A technique called “octant analysis” was used to examine the eddy structure of turbulent and transitional heated boundary layers on flat and curved surfaces. The intent was to identify important ...
Bypass Transition in Boundary Layers Including Curvature and Favorable Pressure Gradient Effects
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Recent experimental studies of two-dimensional boundary layers undergoing bypass transition have been reviewed to attempt to characterize the effects of free-stream turbulence level, acceleration, ...
Measurements in a Transitional Boundary Layer With Görtler Vortices
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The laminar-turbulent transition process has been documented in a concave-wall boundary layer subject to low (0.6 percent) free-stream turbulence intensity. Transition began at a Reynolds number, ...
A Computational Fluid Dynamics Study of Transitional Flows in Low-Pressure Turbines Under a Wide Range of Operating Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A transport equation for the intermittency factor is employed to predict the transitional flows in low-pressure turbines. The intermittent behavior of the transitional flows is taken into account ...
