Near-Wall Modeling of Plane Turbulent Wall Jets
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In most two-dimensional simple turbulent flows, the location of zero shear usually coincides with that of vanishing mean velocity gradient. However, such is not the case for plane turbulent ...
Supersonic Flow Calculations Using a Reynolds-Stress and a Thermal Eddy Diffusivity Turbulence Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A second-order model for the velocity field and a two-equation model for the temperature field are used to calculate supersonic boundary layers assuming negligible real gas effects. The modeled ...
Calculation of Developing Turbulent Flows in a Rotating Pipe
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Internal rotating boundary-layer flows are strongly influenced by large circumferential strain and the turbulence field is anisotropic. This is especially true in the entry region of a rotating ...
Vortex-Induced Vibration Characteristics of Two Fixed-Supported Elastic Cylinders
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Interference effects on vortex-induced vibrations of two side-by-side elastic cylinders, fixed at both ends (with no deflection and displacement) in a cross-flow, were experimentally investigated. ...
Short Duration Heat Transfer Studies at High Free-Stream Temperatures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper describes short duration heat transfer measurements on a flat plate and a gas turbine nozzle airfoil at high free-stream temperatures. A shock tube generated the high-temperature and ...
A Lattice Boltzmann Method Based Numerical Scheme for Microchannel Flows
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Conventional lattice Boltzmann method (LBM) is hyperbolic and can be solved locally, explicitly, and efficiently on parallel computers. The LBM has been applied to different types of complex ...
Modeling Reynolds-Number Effects in Wall-Bounded Turbulent Flows
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Recent experimental and direct numerical simulation data of two-dimensional, isothermal wall-bounded incompressible turbulent flows indicate that Reynolds-number effects are not only present in the ...
