Effect of deflector aerator on stepped spillway flow

Anton Schleiss, Michael Pfister, Stéphane Christian Olivier Terrier

Systematic physical model tests are performed on a stepped spillway equipped with a bottom aerator at the beginning of the stepped part. A deflector is used to issue a jet in order to initiate air entrainment into the flow. A horizontal slot located in the ...

Performance of novel ventilation strategy for capturing CO2 with scheduled occupancy diversity and infiltration rate

Moon Keun Kim

This paper proposes a novel ventilation strategy for capturing CO2 with scheduled occupancy diversity, and changes in recirculating ratio and infiltration rate. While many publications have described filters and a lamp that can efficiently capture and remo ...

Effectiveness of a personalized ventilation system in reducing personal exposure against directly released simulated cough droplets

Dusan Licina

The inhalation intake fraction was used as an indicator to compare effects of desktop personalized ventilation and mixing ventilation on personal exposure to directly released simulated cough droplets. A cough machine was used to simulate cough release fro ...

Air Entrainment in Skimming Flow on Stepped Spillways: the Effect of an Abrupt Slope Change

Anton Schleiss, Michael Pfister, José Pedro Gamito de Saldanha Calado Matos, Mohammad Javad Ostad Mirza

Numerous stepped spillways were built during the last decades. In particular, a stepped spillway may be integrated economically into the downstream face of a RCC gravity dam, or on valley flanks besides embankment or rockfill dams, where slope changes may ...
