Direct Numerical Simulation of Receptivity to Roughness in a Swept-Wing Boundary Layer at High Reynolds Numbers [PDF]

Direct numerical simulations (DNS) are performed to examine the receptivity to roughness in a spatially developing three-dimensional boundary layer over an in finite-swept natural-laminar-flow wing at a free stream Mach number of 0:75 and a chord ...

Low Reynolds number k-ε modeling by using the direct numerical simulation (DNS) data

مجلة علوم ذي قار, 2019
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. Various existing f         µ µ model functions are compared with the DNS data, and a new function is fitted to the high ...

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.

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.
