Index of Resolution Quality for Large Eddy Simulations
(The American Society of Mechanical Engineers (ASME), 2005)In the light of rapidly increasing applications of large-eddy simulations (LES), it is deemed necessary to impose some quality assessment measures for such studies. The verification of LES ... -
Detached-Eddy Simulation of the Separated Flow Over a Rounded-Corner Square
(The American Society of Mechanical Engineers (ASME), 2005)Detached-eddy simulation (DES) is used to study the massively separated flow over a rounded-corner square. The configuration is an idealization of the flow around a forebody cross section rotating ... -
LES of Turbulent Separated Flow and Heat Transfer in a Symmetric Expansion Plane Channel
(The American Society of Mechanical Engineers (ASME), 2005)The LES method was applied to analyze numerically an unsteady turbulent separated and reattached flow and heat transfer in a symmetric expansion plane channel of expansion ratio 2.0. The ... -
Comparative LES and Unsteady RANS Computations for a Periodically-Perturbed Separated Flow Over a Backward-Facing Step
(The American Society of Mechanical Engineers (ASME), 2005)Large eddy simulation and statistical turbulence closures are used to investigate and contrast the ability of both strategies to represent the effects arising from the unsteady perturbation of ... -
A Periodically Perturbed Backward-Facing Step Flow by Means of LES, DES and T-RANS: An Example of Flow Separation Control
(The American Society of Mechanical Engineers (ASME), 2005)Turbulent flow over a backward-facing step, perturbed periodically by alternative blowing∕suction through a thin slit (0.05H width) situated at the step edge, was studied computationally using ... -
Detached-Eddy Simulation of High-Reynolds-Number Beveled-Trailing-Edge Boundary Layers and Wakes
(The American Society of Mechanical Engineers (ASME), 2005)Flow over three different trailing-edge geometries is studied using incompressible detached-eddy simulation and unsteady Reynolds-averaged Navier Stokes CFD methods. Of interest is the ability of ... -
Detached Eddy Simulation of Turbulent Flow and Heat Transfer in a Ribbed Duct
(The American Society of Mechanical Engineers (ASME), 2005)Detached Eddy Simulation (DES) of a hydrodynamic and thermally developed turbulent flow is presented for a stationary duct with square ribs aligned normal to the main flow direction. The rib ... -
Flow Around a Simplified Car, Part 1: Large Eddy Simulation
(The American Society of Mechanical Engineers (ASME), 2005)Large eddy simulations (LES) were made of flows around a generic ground vehicle with sharp edges at the rear end (an Ahmed body with a 25° angle of the rear slanted surface). Separation ... -
Flow Around a Simplified Car, Part 2: Understanding the Flow
(The American Society of Mechanical Engineers (ASME), 2005)Results of a large eddy simulation (LES) are used to explore the flow around a generic car model. A new, refined picture of this flow is established. Many parts and aspects of this flow ... -
The Biased Laminar By-Pass Fluidic Flowmeter
(The American Society of Mechanical Engineers (ASME), 2005)This paper demonstrates that the range of a fluidic flow meter can be significantly extended by connecting it in parallel with a fixed laminar by-pass resistance. Analysis shows how for any ... -
