... number (Re) of 1.68 × 10 5 . Three-dimensional numerical modeling of the riblet structure over a smooth wall is analyzed to study the mechanism responsible for drag-reducing behavior. A maximum reduction of 13.2% in shear stress is observed in the study. The result infers an upward shift in the velocity...

... submerged in liquid, are encountered in a variety of industrial applications [ 2 ]. Numerical modeling of such phenomena has steadily advanced, and along with experiments, it has provided insights into the underlying physics of the processes. For example, Berberovic et al. [ 3 ] used numerical techniques...
