Effect of compressibility on the small-scale structures in isotropic turbulence (2012, methodology): “The simulated compressible turbulence is governed by two important parameters, namely, the Taylor microscale Reynolds number Reλ and the turbulent Mach number Mt (Samtaney et al. 2001).”
Kinetic energy transfer in compressible isotropic turbulence (2018, methodology): “The reference length Lf , velocity Uf , density ρf , pressure pf = ρf U2f , temperature Tf , energy per unit volume ρf U 2 f , viscosity µf and thermal conductivity κf are used respectively (Samtaney et al. 2001; Wang et al. 2012a).”
A bandwidth-optimized WENO scheme for the effective direct numerical simulation of compressible turbulence (2006, methodology): “Resolving the shock thickness is impractical for the detailed simulation of turbulence, as the mean free path is typically orders of magnitude smaller than that of the Kolmogorov length scale [1,2].”
A robust high-order compact method for large eddy simulation (2003, methodology): “5 in [23] are unfiltered values).”
Optimized sixth‐order monotonicity‐preserving scheme by nonlinear spectral analysis (2013, background): “Figure 17 shows the kinetic energy spectral [23] at t D 1.”
DNS and LES of decaying isotropic turbulence with and without frame rotation using lattice Boltzmann method (2005, background): “Since then several numerical investigations of decaying HIT have been carried out, including some recent NS studies on decay exponents and low wave-number spectra [17–20].”
The Statistics of Supersonic Isothermal Turbulence (2007, background): “This suggests that in highly compressible regimes some generalization of the first Kármán-Howarth relation still remains valid, even though a substantial fraction of the specific kinetic energy (up to 1/3 atM = 6) is concentrated in the dilatational component (cf. Moyal 1951; Samtaney et al. 2001).”
