Scaling of the irreducible SO(3)-invariants of velocity correlations in turbulence
Siegfried Grossmann, Detlef Lohse, Achim Reeh
The scaling behavior of the SO(3) irreducible amplitudes of velocity structure tensors (see L'vov, Podivilov, and Procaccia, Phys. Rev. Lett. (1997)) is numerically exam…
Application of extended self similarity in turbulence
Siegfried Grossmann, Detlef Lohse, Achim Reeh
From Navier-Stokes turbulence numerical simulations we show that for the extended self similarity (ESS) method it is essential to take the third order structure function taken with…
Different intermittency for longitudinal and transversal turbulent fluctuations
Siegfried Grossmann, Detlef Lohse, Achim Reeh
Scaling exponents of the longitudinal and transversal velocity structure functions in numerical Navier-Stokes turbulence simulations with Taylor-Reynolds numbers up to $\rel = 110$…
Developed turbulence: From full simulations to full mode reductions
Siegfried Grossmann, Detlef Lohse, Achim Reeh
Developed Navier-Stokes turbulence is simulated with varying wavevector mode reductions. The flatness and the skewness of the velocity derivative depend on the degree of mode reduc…
