Numerical Treatment of Polar Coordinate Singularities
Kamran Mohseni,Tim Colonius +1 more
TLDR
In this paper, a method for treating the coordinate singularity whereby singular coordinates are redefined so that data are differentiated smoothly through the pole, and avoiding placing a grid point directly at the pole is proposed.About:

Progress-variable approach for large-eddy simulation of turbulent combustion
TL;DR: In this paper, a new approach to chemistry modeling for large eddy simulation of turbulent reacting flows is developed instead of solving transport equations for all of the numerous species in a typical chemical mechanism and modeling the unclosed chemical source terms, whereby all of detailed chemical processes are mapped to a reduced system of tracking scalars.

Influence of nozzle-exit boundary-layer conditions on the flow and acoustic fields of initially laminar jets
TL;DR: In this paper, the effects of the nozzle-exit conditions on the flow and sound fields of initially laminar jets are computed by large-eddy simulations (LES) to investigate the effects.

Wavepackets in the velocity field of turbulent jets
TL;DR: In this article, the velocity field of unforced, high Reynolds number, subsonic jets, issuing from round nozzles with turbulent boundary layers, is measured using a hot-wire anemometer and a stereoscopic, time-resolved PIV system.

Large-eddy simulation of the flow and acoustic fields of a Reynolds number 10 5 subsonic jet with tripped exit boundary layers
TL;DR: In this paper, large-eddy simulations of isothermal round jets at a Mach number of 09 and a diameter-based Reynolds number ReD of 105 originating from a pipe are performed using low-dissipation schemes in combination with relaxation filtering.
