Scaling of the velocity profile in strongly drag reduced turbulent flows over an oscillating wall
Published 2016“…Scaling analysis of the velocity profiles in strongly drag reduced flows reveals that the slope of the logarithmic part depends on the amount of drag reduction (DR). …”

Computation fluid dynamics on drag reduction II
Published 2011“…Both the flow pattern in the form of velocity contours and the quantitative drag coefficient are extracted and compared in several ways: single dimple along the wall with depth (h/D = 0.21); multiple (three) dimples along the wall with different separation distances between adjacent dimples; single dimple but with several other h/D ratios (i.e. 0.25, 0.14, 0.10, 0.08). …”

Turbulent Flow over a Flexible Wall Undergoing a Streamwise Traveling Wavy Motion
Published 2005“…For negative c/U, we find that flow separation is enhanced and a large drag force is produced. For positive c/U, the results show that as c/U increases from zero, the separation bubble moves further upstream and away from the wall, and is reduced in strength. …”

An experimental and simulation study of chip transportation behaviour in gundrilling
Published 2017“…From the experiments, terminal velocities of typical gun drill chips at different range of particle Reynolds number were determined to construct the unique drag curve. Based on the findings, a computational fluid dynamic (CFD) numerical model was developed to predict the lateral drag forces with respect to the particle Reynolds number. …”

Comparative study on design of braced excavation systems
Published 2019“…From this study, the following findings are drawn: The Hardening Soil and the Hardening Soil with small-strain stiffness models generate conservative settlement profiles compared to the Mohr-Coulomb model; Combination 1 provides a conservative estimation of the wall bending moments; Upper strut forces are more conservative using DA1 Combination 1 while bottom strut forces are more conservative using DA1 Combination 2 Scheme 1; Scheme 2 gives a large bending moment than Scheme 1; The Mohr-Coulomb model, generally, gives a smaller maximum wall bending moment than the Hardening Soil model; findings from sheet pile excavation deviate from those from diaphragm wall excavations; and lastly, consideration of factored E50/cu ratio produces similar strut forces and bending moments compared to unfactored E50/cu values.…”
