A numerical study of some vortex ring phenomena using direct numerical simulation (DNS)

, 2013
Direct numerical simulation (DNS) is used to study some aspects of the dynamics of vortex rings in viscous, incompressible flow at Reynolds numbers (defined as the ratio of the initial circulation to the kinematic viscosity) in the range of 103 to 104.

Compressible turbulent plane channel DNS datasets

Data in Brief
The database contains detailed statistics of compressible turbulent plane channel (TPC) flow, obtained from direct numerical simulation (DNS), with a very-high-order massively parallel solver of the compressible Navier-Stokes equations.

APPLICATION OF HYBRID CFD/CAA TECHNIQUE FOR MODELING PRESSURE FLUCTUATIONS IN TRANSONIC FLOWS

TASK Quarterly, 2013
Solving AeroAcoustics (CAA) problems by means of the Direct Numerical Simulation (DNS) or even the Large Eddy Simulation (LES) for a large computational domain is very time consuming and cannot be applied widely for engineering purposes.

Struggling with the Modeling of Boundary Layers in Coarse Grids with the Pseudo-Direct Numerical Simulation Method (P-DNS)

Resúmenes de Mecánica Computacional
Flow regions near solid surfaces are strongly dominated by viscosity effects and greatly affected by the near-wall pressure field. The velocity profiles are far from linear and the associated furbulence level and characteristics vary very rapidly in directions normal to the solid boundaries.

Numerical Investigation of a Lifted Flame With Nonequilibrium Scalar Variance and Dissipation Rate Closure Model for Flamelet Generated Manifold

International Journal of Aerospace Engineering
Large eddy simulation (LES) of a turbulent lifted ethylene/nitrogen jet flame in highly-heated coflow is presented. Turbulent combustion modeling is performed by using the flamelet generated manifold (FGM) approach and presumed probability density ...
