Low Reynolds number k-ε modeling by using the direct numerical simulation (DNS) data
University of Thi-Qar Journal of Science, 2008 The constant C and the near-wall damping function f in the eddyviscosityrelation of the k-ε model are evaluated from direct numerical simulation (DNS) data for developed channel and boundary-layer flow, eachat two Reynolds numbers.

DNS Study of Effects of Suddenly-Vanishing Wall Heating in Turbulent Boundary Layer
Journal of Thermal Science and Technology, 2012 The objective of this study is to investigate a thermal field in the turbulent boundary layer by means of direct numerical simulation (DNS), in which the wall heating has suddenly vanished in the downstream region, i.e., the wall is heated by a constant ...

Linear global stability of a confined plume
Theoretical and Applied Mechanics Letters, 2015 A linear stability analysis is performed for a plume flow inside a cylinder of aspect ratio 1. The configuration is identical to that used by Lopez and Marques (2013) for their direct numerical simulation study.

High fidelity numerical simulations of gas turbine flows. [PDF]
, 2018 Traditionally the so called Reynolds-Averaged Navier-Stokes (RANS) and Unsteady RANS (URANS) have been the main numerical tools for computing gas turbine flows due to their computational efficiency and reasonable accuracy.

Multiphase Direct Numerical Simulations (DNS) of Oil-Water Flows Through Homogeneous Porous Rocks
, 2017 Water flooding is commonly used to recover oil from porous rocks using pressurized water. Present study focuses on fully resolved pore-scale level multiphase Direct Numerical Simulations (DNS) of oil-water flows through homogeneous porous rocks. A second order accurate implicit Immersed Boundary Method (IBM) is used to resolve fluid-solid interactions ...
