... 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...

... are suggested based on the results and comparisons are made. The results for both CFD tools suggest that steeper injector nozzle and spear angles than current literature describes will reduce the losses by up to 0.6%. impulse turbine injectors computational fluid dynamics numerical modeling hydropower...

... to the premixed gas-assisted high-pressure atomizer with the previously developed numerical model. This is a two-fluid Eulerian-Eulerian model with a catastrophic phase inversion that was developed for compressible gas-liquid mixtures and can be applied to both the flow through the nozzle-atomizer...

.... Recently, several turbine farm projects have been proposed for tidal or river applications using Darrieus type turbines. Indeed, in water, a particular blade shape can be imagined to minimize the unsteady blade loadings ( 1 2 ). Navier–Stokes cross-flow water turbine numerical modeling unsteady...

... that small and large particles behave differently as they pass through shock diamonds and the bow shock, i.e., in the case of very small particles, as the loading increases, the impact velocity increases, while, for the large particles, the trend is reversed. cold spray fluid dynamics numerical modeling...
