The Dissipation Rate Correlation and Turbulent Secondary Flows in Noncircular Ducts
Publisher: The American Society of Mechanical Engineers (ASME)
The Effect of the Earth’s Rotation on Channel Flow
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The influence that the rotation of the earth has on laminar channel flow is investigated theoretically. The full nonlinear Navier-Stokes equations relative to a reference frame rotating with the ...
Material Frame-Indifference in Turbulence Modeling
Publisher: The American Society of Mechanical Engineers (ASME)
The Freestream Matching Condition for Stagnation Point Turbulent Flows: An Alternative Formulation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The problem of plane stagnation point flow with freestream turbulence is examined from a basic theoretical standpoint. It is argued that the singularity which arises in the standard K –ε model ...
Bounded Energy States in Homogeneous Turbulent Shear Flow—An Alternative View
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The equilibrium structure of homogeneous turbulent shear flow is investigated from a theoretical standpoint. Existing turbulence models, in apparent agreement with physical and numerical experiments, ...
Vortex Simulation of Propagating Stall in a Linear Cascade of Airfoils
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A numerical simulation of propagating stall in a linear cascade of airfoils at high Reynolds numbers is conducted using a vortex method which was first developed by Spalart [7] for this ...
Numerical Study of Turbulent Secondary Flows in Curved Ducts
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The pressure driven, fully developed turbulent flow of an incompressible viscous fluid in curved ducts of square cross-section is studied numerically by making use of a finite volume method. A ...
Local Anisotropy in Strained Turbulence at High Reynolds Numbers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: It is shown that the hypothesis of local isotropy is implausible in the presence of significant mean rates of strain. In fact, it appears that in uniform shear flow near equilibrium, local ...
Assessment of the SSG Pressure-Strain Model in Free Turbulent Jets With and Without Swirl
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Data from free turbulent jets both with and without swirl are used to assess the performance of the pressure-strain model of Speziale, Sarkar and Gatski, which is quadratic in the Reynolds ...
