Surface tension problems solved with the Particle Finite Element Method using large time-steps
TL;DR: In this paper, an extension of PFEM-2 to solve two-phase flows with surface tension was presented. But the authors did not consider the effect of surface tension on the surface tension.
Book ChapterDOI
Turbulence and Its Modelling
TL;DR: Methods for generating turbulence inflow are outlined and it is shown that many of these have limited applicability to complex engineering systems and so suitable strategies proposed.

Flow Investigation and Acoustic Measurements of an Unconfined Turbulent Premixed Jet Flame
TL;DR: In this article, a turbulent jet emanating from an unconfined, premixed burner is investigated by using large eddy simulation (LES) and direct numerical simulation (DNS) as well as experimentally by means of optical (OH* chemiluminescence), acoustic (microphone), and laser-optical measurement techniques (Particle Image Velocimetry).

On the use of spires for generating inflow conditions with energetic coherent structures in large eddy simulation
TL;DR: In this article, the curvilinear immersed boundary method was used to simulate the flow in a wind tunnel with a series of spires in order to investigate the feasibility of numerically developing inflow conditions from a precursory spire LES and assess the similarities of the turbulence statistics to those of an atmospheric boundary layer.

TL;DR: In this paper, a generic burner configuration operated with a turbulent premixed flame is experimentally and numerically investigated to identify relevant source mechanisms and to show the dependence of the noise radiation on the operating conditions.

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.

DIRECT NUMERICAL SIMULATION: A Tool in Turbulence Research
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.
