Computation fluid dynamics on drag reduction II by Zang, Bin

“…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 by Shen, Lian, Zhang, Xiang, Yue, Dick K.P., Triantafyllou, Michael S.

“…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 by Tnay, Guan Leong

“…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. …”
