Characterization of superhydrophobic surfaces for drag reduction in turbulent flow (2018, background): “…wetted asperities that protrude into the flow, as characterized by the wetted roughness rφ , may cause form drag (Kanda, Moriwaki & Kasamatsu 2004; Xie & Castro 2006; Leonardi, Orlandi & Antonia 2007; Leonardi & Castro 2010; Bidkar et al. 2014), increase turbulent mixing and/or enhance turbulent…”
Variation of the Sectional Drag Coefficient of a Group of Buildings with Packing Density (2008, background): “Lien and Yee (2004) and Xie and Castro (2006) have shown that other modified k-e models give little difference.”
Efficient Generation of Inflow Conditions for Large Eddy Simulation of Street-Scale Flows (2008, methodology): “It was developed independently of the work of di Mare et al. (2006) and Veloudis et al. (2007), whose method is similar in some respects, and has already been used elsewhere (Xie & Castro, 2005; Xie & Castro, 2006b).”
Channel flow over large cube roughness: a direct numerical simulation study (2010, background): “On the other hand, since the frictional contribution to total surface stress is below about 7 % provided 0.1 λp 0.25, inadequate wall treatments would not necessarily seriously degrade LES computations of the overall flows in this range of λp (as argued by Xie & Castro 2006).”
Large-Eddy Simulation of Flows over Random Urban-like Obstacles (2008, methodology): “To ensure a largely self-contained paper, a brief description of the numerical methods is given here; more extensive details can be found in Xie & Castro (2006), hereafter denoted by XC.”
Large-Eddy Simulation of the Atmospheric Boundary Layer (2020, unknown): “Large-eddy simulation studies (Kanda et al. 2004b; Xie and Castro 2006; Boppana et al. 2010) of flow and dispersion in urban geometry have demonstrated that the dispersivemomentum (〈u′′w′′〉) and scalar (〈θ ′′w′′〉) fluxes can be significant within theUCL, accounting for 30% or more of the total flux…”
