Reynolds number effects on the Reynolds-stress budgets in turbulent channels [PDF]
, 2008 Budgets for the nonzero components of the Reynolds-stress tensor are presented for numerical channels with Reynolds numbers in the range Reτ ≤180–2000. The scaling of the different terms is discussed, both above and within the buffer and viscous layers ...

Reynolds number dependence of scalar fluctuations in a high Schmidt number turbulent jet [PDF]
, 1991 The scalar rms fluctuations in a turbulent jet were investigated experimentally, using high-resolution, laser-induced fluorescence techniques. The experiments were conducted in a high Schmidt number fluid (water), on the jet centerline, over a jet ...

High-Reynolds number Taylor-Couette turbulence. [PDF]
, 2016 Taylor-Couette flow, the flow between two coaxial co- or counter-rotating cylinders, is one of the paradigmatic systems in the physics of fluids. The (dimensionless) control parameters are the Reynolds numbers of the inner and outer cylinders, the ratio ...

A new friction factor relationship for fully developed pipe flow [PDF]
, 2005 The friction factor relationship for high-Reynolds-number fully developed turbulent pipe flow is investigated using two sets of data from the Princeton Superpipe in the range 31×10^3 ≤ ReD ≤ 35×10^6. The constants of Prandtl’s ‘universal’ friction factor
