Algebraic proof and application of Lumley's realizability triangle
G. A. Gerolymos, I. Vallet
Lumley [Lumley J.L.: Adv. Appl. Mech. 18 (1978) 123--176] provided a geometrical proof that any Reynolds-stress tensor (indeed any tensor whose eigenvalues ar…
Further analysis of the budgets of the dissipation tensor in turbulent plane channel flow
G. A. Gerolymos, I. Vallet
Recent DNS results [Gerolymos G.A., Vallet I. : J. Fluid Mech. 807 (2016) 386--418] have provided data for the terms in the transport equations for the components of the dissipatio…
The dissipation tensor in wall turbulence
G. A. Gerolymos, I. Vallet
The paper investigates the dissipation tensor in wall turbulence. Available DNS data are examined to illustrate the differences in the anisotropy of the dissipat…
Reynolds-stress model prediction of 3-D duct flows
G. A. Gerolymos, I. Vallet
The paper examines the impact of different modelling choices in second-moment closures by assessing model performance in predicting 3-D duct flows. The test-cases (developing flow…
Pressure, density, temperature and entropy fluctuations in compressible turbulent plane channel flow
G. A. Gerolymos, I. Vallet
We investigate the fluctuations of thermodynamic state-variables in compressible aerodynamic wall-turbulence, using results of direct numerical simulation (DNS) of compressible tur…
Hybrid low-diffusion approximate Riemann solvers for Reynolds-stress transport
N. Ben Nasr, G. A. Gerolymos, I. Vallet
The paper investigates the use of low-diffusion (contact-discontinuity-resolving [Liou M.S.: {\em J. Comp. Phys.} {\bf 160} (2000) 623--648]) approximate Riemann solvers for the co…
