Large-scale motions in a supersonic turbulent boundary layer (2006, background): “The length scales found are at least 4 times larger than the λux computed for the same contour level in an incompressible boundary layer by Ganapathisubramani et al. (2005) at Reθ = 2500.”
Very-large-scale motions in a turbulent boundary layer (2010, methodology): “For more information, refer to the following papers that describe these packet motions extensively (e.g. Ganapathisubramani et al. 2005; Hutchins, Hambleton, Marusic 2005; Wu & Christensen 2006).”
A predictive inner–outer model for streamwise turbulence statistics in wall-bounded flows (2011, background): “…simulations have highlighted the presence in the log region of pronounced and elongated regions of low- and high-speed fluctuations (Ganapathisubramani, Longmire & Marusic 2003; del Álamo & Jiménez 2003; Tomkins & Adrian 2003; Ganapathisubramani et al. 2005; Hambleton, Hutchins & Marusic 2006).”
Vortical structures in the turbulent boundary layer: a possible route to a universal representation (2008, background): “Thus, vortices are obviously associated with wider and wider regions of coherent longitudinal velocity with increasing wall-distance, consistently with the structure and scale growth found in the spanwise direction by Tomkins & Adrian (2003) and Ganapathisubramani et al. (2005).”
Flow physics and RANS modelling of oblique shock/turbulent boundary layer interaction (2013, background): “Indeed, the length scale of the incompressible boundary layer described by Ganapathisubramani et al. (2005) at Reθ = 2500 was found to be four times smaller than the length scale of the compressible boundary layer at Reθ = 38 000 described in Ganapathisubramani et al. (2006).”
Large-scale influences in near-wall turbulence (2007, background): “PIV studies of streamwise–spanwise planes by Ganapathisubramani et al. (2003), Tomkins & Adrian (2003) and Hambleton et al.”
Large-scale and very-large-scale motions in turbulent pipe flow (2006, background): “Particle image velocimetry measurements (Adrian et al. 2000; Tomkins & Adrian 2003; Ganapathisubramani et al. 2005) support the picture of packets of hairpins creating long streaks of low-momentum fluid in the outer layer by lifting low-speed fluid upwards, in much the same way as the near-wall quas”
Eulerian and Lagrangian views of a turbulent boundary layer flow using time-resolved tomographic PIV (2011, methodology): “There is a connection between these streaky u-formations and the presence of negative and positive v, especially closer to the wall, see e.g. two-point correlations from Ganapathisubramani et al. (2005).”
Turbulence structure in a boundary layer with two-dimensional roughness (2009, methodology): “The same averaging techniques were used by Tomkins & Adrian (2003) and Ganapathisubramani et al. (2005).”
Towards Reconciling the Large-Scale Structure of Turbulent Boundary Layers in the Atmosphere and Laboratory (2012, methodology): “In the laboratory, hairpin vortices have been well-documented (for example Adrian et al. 2000b; Christensen and Adrian 2001; Ganapathisubramani et al. 2003, 2005; Lee and Sung 2011) while in the ASL the evidence, though suggestive of such features, has been less conclusive (Hommema and Adrian 2003;…”
Spatial structure of a turbulent boundary layer with irregular surface roughness (2010, background): “As noted in many recent studies (see e.g. Christensen & Adrian 2001; Tomkins & Adrian 2003; Ganapathisubramani et al. 2005), spatial correlations involving two or more points of interest contain a wealth of information regarding the average spatial structure of wall turbulence.”
Direct numerical simulation of the turbulent boundary layer over a cube-roughened wall (2010, result): “These results are consistent with those of Ganapathisubramani et al. (2005), who showed that the extent of the streamwise coherence drops off significantly beyond the log layer.”
Inclined cross-stream stereo particle image velocimetry measurements in turbulent boundary layers (2005, methodology): “Two-point correlations in the spanwise/streamwise plane are presented in Tomkins & Adrian (2003) and Ganapathisubramani et al. (2005).”
Three-dimensional instantaneous structure of a shock wave/turbulent boundary layer interaction (2009, result): “The spanwise velocity component appears much less coherent along both the streamwise and spanwise directions in comparison to the streamwise component, consistent with the two-point correlations made by Ganapathisubramani et al. (2005) in their incompressible turbulent boundary layer.”
Evidence of very long meandering features in the logarithmic region of turbulent boundary layers (2007, background): “These features form the stripiness noted in PIV experiments that has been previously related to the hairpin packet paradigm and shown to carry a large proportion of the Reynolds shear stress in the log region (Ganapathisubramani et al. 2003; Marusic & Hutchins 2006). These may be what Kim & Adrian (”
