The main goal of AFC4Hydro research project is to design, implement and validate in full-scale water turbine an active flow control system that permit to increase efficiency and reduce the dynamics loads on the structure at any off-design operating conditions and during transient operations.

IPM measurements at Oksla

IPM measurements at Oksla

During week 41, LTU team has been at Oksla in an attempt to mitigate the rotating vortex rope using the IPM system.

LTU is getting ready for Oksla measurements

On Thursday the 28th of September the two IPM rods were dismantled from the Porjus U9 draft tube.


Our work packages

What We Do

Injection of Pulsating Momentum

The objective of this work package is to investigate the possibility to mitigate pressure pulsations in hydraulic turbine by the injection of pulsating momentum (IPM).

Injection of Continuous Momentum

This project aims at evaluating and verifying second generation Injection of Continuous Momentum (ICM) technologies for the mitigation and control of pressure pulsations in a hydro-turbine draft tube.

Structural Health Monitoring

The objective of this work package is to investigate the dynamic behavior of an hydraulic turbine operating at off-design and at transient conditions, and to develop a structural health monitoring system (SHM).

Active Flow Control

This work package will merge the different concepts developed in WP1 (IPM), WP2 (ICM) and WP3 (SHM) as well develop a controller system for online multi-objective optimization to create the active flow control system (AFC).

Exploitation and Dissemination

This work package consists in managing the Plan for Exploitation and Dissemination of Results, in order to make the results and information generated in this project open for the public.


This work package will serve to manage, administrate and coordinate the project effectively in order to execute the planned tasks and to achieve the milestones.
