    Computation fluid dynamics on drag reduction II by Zang, Bin

    Published 2011
    “…In this project, a number of Reynolds-Average Navier-Stokes (RANS) models are verified with benchmark values of Direct Numerical Solutions (DNS) provided by the past research to identify appropriate RANS models which allow the simulation of dimpled flow with specific Reynolds number and initial conditions in a 3D channel. Five RANS turbulence models: Spalart-Allmaras (Vorticity-based production); Spalart-Allmaras (Strain / Vorticity-based production); k-ε Standard (Enhanced Wall Treatment); k-ε Realizable (Enhanced Wall Treatment) and k-ω Standard (Shear Flow Correction), are chosen after comparing with DNS data published by Moser et al (1999). [20] Subsequently, the single and multiple dimpled channel flows are modeled and simulated by the five RANS models chosen in the verification stage with periodic boundary condition, a Reynolds number of 20000, and a three-dimensional channel of L = 1.5 m, B = 0.454 m and H = 1 m. …”

    Turbulent Flow over a Flexible Wall Undergoing a Streamwise Traveling Wavy Motion by Shen, Lian, Zhang, Xiang, Yue, Dick K.P., Triantafyllou, Michael S.

    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. …”

    Characteristics of bubble rise in a liquid by Tan, Si Ying

    Published 2022
    “…Simultaneously, the trajectory and the bubble shape, in terms of aspect ratio, are observed to be highly dependent on both bubble size and fluid viscosity, which affects the components of a drag force. Slight deviations from the standard drag coefficient curve for a solid sphere could be due to the differences in aspect ratio which affect the bubble frontal area given that the bubble volume remains constant.…”

    Seepage effects on settling velocity by Goh, Alvin Hanchang.

    Published 2009
    “…Uniform plastic spherical particles of varying diameters (0.630cm, 0.790cm, 0.950cm and 1.285cm) and densities under different seepage inflow rates (0 m3/s, 1X10-4 m3/s, 2X10-4 m3/s and 5X10-4 m3/s) are used. The drag coefficient is the most important property in the mechanics of particle motion and fluid dynamics because most particles in real life are employed either to overcome or to utilize the drag caused by the fluid. …”
