Journal ArticleDOI
Direct numerical simulation of decaying compressible turbulence and shocklet statistics
TL;DR: In this article, the authors presented results from 1283 and 2563 direct numerical simulations (DNS) of decaying compressible, isotropic turbulence at fluctuation Mach numbers of Mt∼0.1-0.5 and at Taylor Reynolds numbers Reλ=O(50-100).
Journal ArticleDOI
Large-eddy simulation and multiscale modelling of a Richtmyer–Meshkov instability with reshock
TL;DR: In this paper, large-eddy simulations of the Richtmyer-Meshkov instability with reshock are pre- sented and the results are compared with experiments, where statistics of the unresolved scales of the flow are estimated.
Journal ArticleDOI
A comparison of vortex and pseudo-spectral methods for the simulation of periodic vortical flows at high Reynolds numbers
TL;DR: Using a fourth order accurate kernel for interpolation between the particles and the mesh, the results of the hybrid vortex method and of the pseudo-spectral method agree well in both flow cases.
Journal ArticleDOI
Large-eddy simulation and wall modelling of turbulent channel flow
Daniel Chung,Dale Pullin +1 more
TL;DR: In this paper, a special near-wall subgrid-scale (SGS) model based on wall-parallel filtering and wall-normal averaging of the streamwise momentum equation was developed, with an assumption of local inner scaling used to reduce the unsteady term.
Journal ArticleDOI
A low numerical dissipation patch-based adaptive mesh refinement method for large-eddy simulation of compressible flows
TL;DR: A conservative, flux-based hybrid numerical method that uses both centered finite-difference and a weighted essentially non-oscillatory (WENO) scheme is given, encompassing the cases of scheme alternation and internal mesh interfaces resulting from SAMR.
