A new inflow turbulence generator for large eddy simulation evaluation of wind effects on a standard high-rise building
TL;DR: In this paper, a narrowband synthesis random flow generator (NSRFG) was proposed for large eddy simulation of atmospheric boundary layer (ABLBP) flow. And the new technique was then applied to the numerical simulation of the turbulent flow around the CAARC standard building model, which was tested in the boundary layer wind tunnel of the South China University of Technology.

Spatially Developing Supersonic Turbulent Boundary Layer with a Body-Force-Based Method
TL;DR: In this paper, a spatially developing equilibrium supersonic turbulent flat-plate boundary layer suitable for direct numerical simulations or large-eddy simulations of viscous/inviscid interactions is described.

Analysis of Converging-Diverging Beveled Nozzle Jets Using Large Eddy Simulation with a Wall Model
TL;DR: In this paper, a wall model based on the logarithmic velocity profile was developed and validated for nearly incompressible flat plate boundary layers (BLs) for simulations of converging-diverging (CD) nozzles for supersonic jet aeroacoustics predictions.
Journal ArticleDOI
On the importance of generating accurate turbulent boundary condition for unsteady simulations
TL;DR: A comparison of the digital filter-based turbulent inflow data generation technique with three different methods within the framework of the large eddy simulations technique using the fifth-and second-order accurate methods in space and time, respectively, is presented in this paper.

How to estimate the resolution of an LES of recirculating flow
TL;DR: In this paper, two-point correlations are used to estimate the resolution of an LES in a plane asymmetric diffuser and decaying grid turbulence, and the main conclusions are that two point correlations are the best way to estimate resolution and that energy spectra are not suitable.

The theory of homogeneous turbulence
TL;DR: In this article, the kinematics of the field of homogeneous turbulence and the universal equilibrium theory of decay of the energy-containing eddies are discussed. But the authors focus on the dynamics of decay and not on the probability distribution of u(x).
Journal ArticleDOI
Direct numerical simulation of free-surface and interfacial flow
TL;DR: In this paper, the authors consider the formation of droplet clouds or sprays that subsequently burn in combustion chambers, which is caused by interfacial instabilities, such as the Kelvin-Helmholtz instability.

Direct simulation of a turbulent boundary layer up to R sub theta = 1410
TL;DR: In this paper, the turbulent boundary layer on a flat plate, with zero pressure gradient, is simulated numerically at four stations between R sub theta = 225 and R sub tta = 1410.

Parviz Moin,Krishnan Mahesh +1 more
TL;DR: In this article, direct numerical simulation (DNS) of turbulent flows has been reviewed and the complementary nature of experiments and computations in turbulence research has been illustrated, as well as how DNS has impacted turbulence modeling and provided further insight into the structure of turbulent boundary layers.
