Webinar IAHR Water Monograph on Vortex-Flow Intakes 

Thursday, 4 December 2023 | 2 p.m. CET

Open Access IAHR Water Monograph Series

#WaterMonographs

The Open Access IAHR Water Monograph Series presents information on physical processes, measurement techniques, theoretical material, numerical modeling techniques, engineering applications, and historical and cultural matters in an appealing, readable, and well-illustrated manner.

Webinar IAHR Water Monograph on Vortex-Flow Intakes 

This Water Monograph shows how designers use swirl and vortex generation to design vortex-flow intakes used to create vortex flows in dropshafts. Special focus is given to tangential vortex intakes, as this form is becoming especially common in urban areas. In addition, this monograph considers when swirl and vortex formation are undesired for intakes, especially submerged intakes such as used for hydropower and pumps. In so doing, this monograph serves as an update of the valuable 1987 IAHR monograph. The use of vortex-flow intakes has grown substantially since IAHR’s original monograph and will continue to grow in the foreseeable future.

Attendees will get a comprehensive overview of the hydraulics of swirling flows commonly encountered in vortex dropshafts, reservoir intakes, and pump intakes.

This webinar is aimed at:  

• Researchers 
  

• Hydraulic modellers,  
  

• Engineers working with swirling flows and vortex intake design
