Growing demands for energy are motivating researchers to conduct in-depth analysis of
positive displacement machines such as oil-injected screw compressors which are …

The traditional approach for the hydrodynamic characterization of the flow down stepped
spillways is through physical modeling, which is susceptible to scale effects and has …

This work presents a numerical study of a skimming flow regime in a stepped spillway
structure, which is a complex two-phase flow with self-aeration phenomenon. The numerical …

The main features that attract hydraulic engineers for designing stepped spillways are their
ability to lose a large portion of the flow energy and add or increase aeration to the flow …

Using stepped chutes as a structure for controlling flood discharges is applicable for long
time. Measuring the depth of flow over that structure is essential for designing of the side …

Piano Key Weirs (PKWs) are an improvement of labyrinth key weirs. This type of weir can be
placed on the dams needing to be restored, which is an advantage given the number of …

Estudos experimentais desenvolvidos ao longo dos anos caracterizaram o escoamento
sobre diferentes configurações de vertedouros em degraus. Por outro lado, a modelagem …

Water is an imperative source to human life. The change in climate is affecting the
availability of water round the year which combined with increasing water demand has …

Stepped spillway is hydraulic structure designed to dissipate considerable kinetic energy
because it's characterised by the large value of the surface roughness. On stepped chutes …
