Coherent structures in wall-bounded turbulence (2017, background): “Hutchins & Marusic (2007) have proposed that real streamwise-velocity eddies may be very long, meandering on a shorter scale.”
Logarithmic scaling of turbulence in smooth- and rough-wall pipe flow (2013, background): “It is worth noting, however, that its rate of increase has not yet been established with any certainty, where, for example Hutchins & Marusic (2007) proposed an increase in peak u2+ of 2.22 per decade in Reτ , while Marusic, Mathis & Hutchins (2010a) suggest a possible value as low as 0.90 per…”
Effects of micro-ramps on a shock wave/turbulent boundary layer interaction (2009, result): “The present flow organization is also consistent with results found in incompressible boundary layers using hot-film/wire anemometry (see [28,29]) and planar PIV [30,31].”
Low-frequency dynamics of shock-induced separation in a compression ramp interaction (2009, methodology): “The regions of uniform speed are similar to those found in incompressible boundary layers by Hutchins & Marusic (2007), where the authors reconstructed the spatial extent using Taylor’s hypothesis with time series data obtained using a spanwise rake of hotwire/sonic anemometers in a variety of…”
Towards Reconciling the Large-Scale Structure of Turbulent Boundary Layers in the Atmosphere and Laboratory (2012, methodology): “However, a comparison of the Ruu results from Hutchins and Marusic (2007a) for varying z/δ suggest that there should be very little change between 3 Dennis and Nickels (2008) showed that Taylor’s approximation is accurately applicable when the projection distances are small (< 6δ) and only the…”
Direct numerical simulation of turbulence in a nominally zero-pressure-gradient flat-plate boundary layer (2009, background): “Numerous experimental and theoretical studies on the statistics and structures of turbulent ZPGFPBL are available in the literature dated as early as Coles (1956), Favre, Gaviglio & Dumas (1957), and as recent as Hutchins & Marusic (2007), Monkewitz, Chauhan & Nagib (2007).”
Direct numerical simulation of hypersonic turbulent boundary layers. Part 3. Effect of Mach number (2011, background): “…play a key role in wall-bounded turbulent flows at incompressible and compressible conditions (Robinson 1991; Spina, Smits & Robinson 1994; Kim & Adrian 1999; Adrian, Meinhart & Tomkins 2000; Ganapathisubramani, Clemens & Dolling 2006; Hutchins & Marusic 2007; Ringuette, Wu & Martı́n 2008).”
Effects of upstream boundary layer on the unsteadiness of shock-induced separation (2006, methodology): “Recently, Hutchins & Marusic (2007) performed experiments using a rake of sonic anemometers in an atmospheric turbulent boundary layer in the salt flats in Utah (where the Reynolds number is approximately 106) and found signatures of similar elongated low- and high-speed regions.”
The three-dimensional structure of momentum transfer in turbulent channels (2011, background): “The appearance of the latter clearly suggests a composite character, and it is difficult not to remark its similarity with the large-scale low-velocity streaky structures discussed, for example, by Hutchins & Marusic (2007a), or in figure 4 of Flores et al. (2007).”
Colour of turbulence (2016, background): “One such example is that of boundary layer flows where experiments (Hutchins & Marusic 2007b; Mathis et al. 2009; Monty et al. 2009; Guala et al. 2011; Marusic et al. 2013) and simulations (Wu & Moin 2009; Schlatter & Örlü 2010; Sillero, Jiménez & Moser 2013, 2014) have provided insight into…”
Velocity statistics in turbulent channel flow up to $Re_{\tau }=4000$ (2014, methodology): “This feature is difficult to observe in experiments, which typically can only access streamwise spectra upon use of Taylor’s hypothesis, and it is likely caused by the activation of the outer-layer modes through a transient growth mechanism (del Álamo & Jiménez 2006; Hutchins & Marusic 2007).”
Universal aspects of small-scale motions in turbulence (2010, background): “…in the streamwise direction (>10δ) compared to their typical spanwise dimension (∼0.5δ) and although they tend to meander, they are predominantly oriented in the streamwise direction making them easy to detect in hotwire and planar velocity measurements (Hutchins & Marusic 2007; Monty et al. 2007).”
Simulations of Spatially Evolving Turbulent Boundary Layers up to Reθ = 4300 (2010, background): “…studies by Kim and Adrian (1999) who identified very large-scale structures in pipe flows, motivated the subsequent analysis of large-scale motions in channel, pipe and boundary-layer flows by many authors (see e.g. Hutchins and Marusic (2007a); Guala et al. (2006); del Álamo and Jiménez (2003)).”
Turbulent fluctuations above the buffer layer of wall-bounded flows (2008, methodology): “Most of the detailed discussion in this paper is based on the turbulent channel simulations of del Álamo & Jiménez (2003), del Álamo et al.”
Large-scale amplitude modulation of the small-scale structures in turbulent boundary layers (2009, methodology): “In this paper, we expand upon the initial observations of Hutchins & Marusic (2007 b ), using the Hilbert transformation in an attempt to quantify the relationship between large-scale ﬂuctuations and any amplitude modulation of the small-scale energy in turbulent boundary layers.”
