Direct Numerical Simulation of Supersonic Turbulent Boundary Layer Flow
TL;DR: In this article, a spatially evolving supersonic flat-plate turbulent boundary layer flow with free Mach number M∞ = 2.25 and Reynolds number Re = 365000/in is simulated.
Journal ArticleDOI
Direct Numerical Simulation of a Spatially Evolving Supersonic Turbulent Boundary Layer at Ma = 6
LI Xin-Liang,Fu Dexun,Ma Yanwen +2 more
TL;DR: In this paper, a spatially evolving supersonic turbulent boundary layer at free-stream Mach number 6 was modeled using the seventh-order WENO scheme for convection terms of Navier-Stokes equations and fine mesh was adopted to minimize numerical dissipation.
Journal ArticleDOI
Numerical solution of the incompressible Navier-Stokes equations with an upwind compact difference scheme
TL;DR: A new finite difference method for the discretization of the incompressible Navier-Stokes equations is presented and validation of the method by computation of Taylor's vortex array shows that it has high resolving efficiency.
Journal ArticleDOI
Direct numerical simulation of compressible isotropic turbulence
LI Xin-Liang,Fu Dexun,Ma Yanwen +2 more
TL;DR: In this paper, a direct numerical simulation of decaying compressible isotropic turbulence at turbulence Mach numbers of M t = 0.2-0.7 and Taylor Reynolds numbers of 72 and 153 is performed by using the 7th order upwind-biased difference and 8th order center difference schemes.
Journal ArticleDOI
Acoustic Calculation for Supersonic Turbulent Boundary Layer Flow
TL;DR: In this article, an approach which combines direct numerical simulation (DNS) with the Lighthill acoustic analogy theory is used to study the potential noise sources during the transition process of a Mach 2.25 flat plate boundary layer.
