RISHybrid RANS–LES Simulation of Turbulent Heat Transfer in a Channel Flow With Imposed Streamwise or Spanwise Mean Temperature Gradient
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Computational fluid dynamics (CFD) results are presented for turbulent flow and heat transfer in a plane channel. This study investigates an idealized fully developed planar channel flow case for which the mean velocity ...
Evaluation of a Statistically Targeted Forcing Method for Synthetic Turbulence Generation in Scale-Resolving Simulations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Computational fluid dynamics (CFD) results are presented for synthetic turbulence generation by a proposed statistically targeted forcing (STF) method. The new method seeks to introduce a fluctuating velocity field with a ...
Scale-Resolving Simulations of a Statistically Targeted Forcing Method for Synthetic Turbulence Generation in a Freestream Turbulence
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Computational fluid dynamics results for synthetic turbulence generation of freestream turbulence by a proposed statistically targeted forcing (STF) method are presented. The STF method has been previously documented for ...
Static and Dynamic Time Filtering Techniques for Hybrid RANS-Large Eddy Simulation of Non-Stationary Turbulent Flows
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Unsteady turbulent wall bounded flows can include complex flow physics such as temporally varying mean pressure gradients, intermittent regions of high turbulence intensity, and interaction of different scales of motion. ...
