Numerical Simulation of Unsteady Wake/Blade Interactions in Low-Pressure Turbine Flows Using an Intermittency Transport Equation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An extensive computational investigation of the effects of unsteady wake/blade interactions on transition and separation in low-pressure turbines has been performed by numerical simulations of two ...
Modeling of Flow Transition Using an Intermittency Transport Equation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A new transport equation for intermittency factor is proposed to model transitional flows. The intermittent behavior of the transitional flows is incorporated into the computations by modifying ...
A Comparison of Algebraic and Differential Second-Moment Closures for Axisymmetric Turbulent Shear Flows With and Without Swirl
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Computations are reported for three axisymmetric turbulent jets, two of which are swirling and one containing swirl-induced recirculation, obtained with two models of turbulence: a differential ...
A Correlation-Based Transition Model Using Local Variables—Part I: Model Formulation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A new correlation-based transition model has been developed, which is based strictly on local variables. As a result, the transition model is compatible with modern computational fluid dynamics ...
A Correlation-Based Transition Model Using Local Variables—Part II: Test Cases and Industrial Applications
Publisher: The American Society of Mechanical Engineers (ASME)
