• Large-Eddy Simulation of Flows over Random Urban-like Obstacles (2008, methodology): “Flow over regular arrays of cubes mounted on a wall has been studied by a number of researchers (Meinders & Hanjalić, 1999; Hanna et al., 2002; Cheng & Castro, 2002; Stoesser et al., 2003; Kanda et al., 2004; Coceal et al., 2006).”
• Exponential roughness layer and analytical model for turbulent boundary layer flow over rectangular-prism roughness elements (2016, methodology): “Having available the friction velocity uτ , we take the mean velocity profiles above the roughness elements and fit a logarithmic law determining the hydrodynamic roughness height zo and displacement d from the regression, as done also in Cheng & Castro (2002) and Kanda, Moriwaki & Kasamatsu (2004).”
• Channel flow over large cube roughness: a direct numerical simulation study (2010, methodology): “The figure shows the cases λp = 0.25, the subject of considerable earlier experimental and numerical work (e.g. Cheng & Castro 2002: Coceal et al. 2006) and λp =0.11.”
• Momentum Transfer within Canopies (2008, background): “Wind tunnel experiments demonstrate that the dispersive fluxes can be neglected in dense canopies across the entire depth of canopy (Poggi et al. 2004a; Cheng and Castro 2002; Raupach et al. 1986).”

• Turbulence structure in a boundary layer with two-dimensional roughness (2009, methodology): “Also shown are the two-dimensional roughness results of Krogstad & Antonia (1999), who used rods spaced at p/k =4, and the three-dimensional roughness results of Cheng & Castro (2002), who used staggered rows of cubes spaced at p/k = 2 in both the streamwise and spanwise directions.”
• Oscillatory flow through submerged canopies: 1. Velocity structure (2005, background): “For example, it is common to define the drag coefficient Cdh based on a reference velocity measured at the top of the canopy z = hc [e.g., Cheng and Castro, 2002; Ghisalberti and Nepf, 2004].”
• Roughness Lengths for Momentum and Heat Derived from Outdoor Urban Scale Models (2007, methodology): “Indoor experiments by Cheng and Castro (2002) demonstrated that zm significantly changed with IBL/H, especially when IBL/H 10.”

• Rough-wall boundary layers: mean flow universality (2007, background): “…within the roughness sublayer where the flow is spatially inhomogeneous, individual profiles are not necessarily logarithmic, it has been shown that spatially averaged mean velocities (at each height) do conform to extensions of the log-law region in the inertial layer above (Cheng & Castro 2002).”
