- Instabilities in Viscosity-Stratified Flow (2014, background): “…thinning combined with elastic effects, and in many of the mechanisms proposed, it appears that the role of elasticity in achieving this reduction is crucial, for example, in the attainment of the maximum drag-reduction asymptote (Ptasinski et al. 2003, Sreenivasan & White 2000, Xi & Graham 2010).”
- On the coherent drag-reducing and turbulence-enhancing behaviour of polymers in wall flows (2004, background): “In drag-reduced flow, the maximum of u′+ x is higher than or comparable with the DR = 0% case, as found in experiments (Warholic et al. 1999; Ptasinski et al. 2003; White et al. 2004).”
- Drag reduction by polymer additives in a turbulent channel flow (2003, unknown): “This figure also suggests that the FENE-P model with L2 = 1000, adopted by Ptasinski et al. (2002), shows a similar behaviour to that of the Oldroyd-B model.”
- Turbulent drag reduction in dam-break flows (2004, background): “…et al. 2003a, 2003b; L’vov et al. 2003; Benzi et al. 2004) and direct numerical simulations (Housiadas and Beris 2003; Min et al. 2003a, 2003b; Ptasinski et al. 2003; De Angelis et al. 2003) reproduce important aspects of dilute polymer dynamics, such as the onset of drag reduction,…”
- Influence of rheological parameters on polymer induced turbulent drag reduction (2006, methodology): “Normalized by all stress τw(= ρU2 τ ) the time averaged shear stress balance quation is given by [6,7,11]:”
- Saltating particles in a turbulent boundary layer: experiment and theory (2009, background): “Associated with this is a decrease in the fluid shear stress at the bed with increasing wind speed (Ptasinski et al. 2003)”
- Effects of polymer stresses on eddy structures in drag-reduced turbulent channel flow (2006, result): “Over the past decade direct numerical simulations (DNS) of turbulent flows, using various models of non-Newtonian fluid rheology to model the effect of adding polymers, have shown good agreement with experimental observations (Sureshkumar et al. 1997; Dimitropoulos et al. 1998, 2001; de Angelis, Cas”
