Abstract: The effects of unsteadiness in the turbulent flow through a staggered array of circular cylinders, modeling an ultraviolet disinfection system, are studied by means of solutions of the two-dimensional Reynolds-averaged ...

Abstract: The effect on flow resistance in uniform flat‐bed open‐channel flows due to suspended sediment is investigated. Flows with and without an equilibrium sand bed are studied in a laboratory channel. Three well‐sorted natural ...

Abstract: Unsatisfactory features of the equation that is recommended in a standard reference on bridge scour (commonly known as HEC-18) for predicting pressure-flow scour are pointed out. These are found to stem from the basic model ...

Abstract: The homogeneous surface-diffusion model (HSDM) and the pore-surface-diffusion model (PSDM) for adsorption on granular activated carbon in a completely mixed batch reactor are examined in the near-equilibrium regime. In ...

Abstract: The turbulence characteristics of sediment‐laden flows in open channels are investigated using two‐component laser‐Doppler velocimetry. Suspensions of well‐sorted sands with diameters ranging from 0.15 mm to 0.24 mm, flowing ...

Abstract: Measurements of mean and turbulence characteristics in uniform open‐channel flows of constant mean depth over artificial fixed one‐dimensional periodic bed features were obtained using two‐component laser‐Doppler velocimetry. ...
