SpillwayPro: Integrated Water Surface Profile, Cavitation, and Aerated Flow Analysis for Smooth and Stepped Chutes

open access: yesWater (Switzerland), 2022
Spillways of large and small dams experience flow conditions that exceed the capabilities of common water surface profile computer programs. Unique channel geometries, steep slopes, and streamline curvature demand rigorous mathematics, while phenomena ...

A Comparative Performance Evaluation of Mainstream Multiphase Models for Aerated Flow on Stepped Spillways

open access: yesWater (Switzerland)
A systematic comparative evaluation of mainstream multiphase models for specific hydraulic structures is essential to investigate aerated flow characteristics and promote the models’ application. However, such evaluations remain scarce.

Capturing Free Surface Dynamics of Flows over a Stepped Spillway Using a Depth Camera [PDF]

open access: yesSensors
Spatio-temporal measurements of turbulent free surface flows remain challenging with in situ point methods. This study explores the application of an inexpensive depth-sensing RGB-D camera, the Intel® RealSense™ D455, to capture detailed water surface ...

Effect of PEEP on lung aeration in pediatric patients after cardiac surgery: a CT-Based study [PDF]

open access: yesBrazilian Journal of Anesthesiology
Background: Loss of lung aeration is frequently observed in adult patients following cardiac surgery with cardiopulmonary bypass. Yet, in children, changes in lung aeration following surgical repair of congenital heart defects, and the effects of ...

Evapotranspiration dynamics in aerated and non-aerated subsurface flow treatment wetlands

open access: yesScience of The Total Environment, 2022
This study reports the seasonal dynamics of evapotranspiration (ET) and evaporation (E) in different subsurface flow treatment wetlands operating in a temperate European climate. Daily water balances were compiled over the course of ten years (August 2010-July 2020). The study includes non-aerated horizontal flow wetlands (25 cm deep and 50 cm deep) as
