Numerical simulations of possible finite time singularities in the incompressible Euler equations: comparison of numerical methods
Tobias Grafke, Holger Homann, Juergen Dreher +1
The numerical simulation of the 3D incompressible Euler equation is analyzed with respect to different integration methods. The numerical schemes we considered include spectral met…
Impact of the floating-point precision and interpolation scheme on the results of DNS of turbulence by pseudo-spectral codes
Holger Homann, Jürgen Dreher, Rainer Grauer
In this paper we investigate the impact of the floating-point precision and interpolation scheme on the results of direct numerical simulations (DNS) of turbulence by pseudo-spectr…
A Corrsin type approximation for Lagrangian fluid Turbulence
Rudolf Friedrich, Rainer Grauer, Holger Homann +1
In Lagrangian turbulence one is faced with the puzzle that 2D Navier-Stokes flows are nearly as intermittent as in three dimensions although no intermittency is present in the inve…
Lagrangian Statistics of Navier-Stokes- and MHD-Turbulence
H. Homann, R. Grauer, A. Busse +1
We report on a comparison of high-resolution numerical simulations of Lagrangian particles advected by incompressible turbulent hydro- and magnetohydrodynamic (MHD) flows. Numerica…
