First public summary of internal meetings and workshops

Document summarizing the conclusions of the internal meetings and workshops carried out during the previous 12 months Deliverable related to Task 53

Report from the optimisation tool implemented on the down-scale test rig and SHM system

Document reporting the results of the sensitivity analysis performed on the downscale test rig and SHM system For example the relative decrease of the pressure pulsations in the draft tube and the efficiency with the IPMICM system versus no IPMICM system will be key parameters Moreover the report will include the required tuning and scaling procedure that will facilitate the appellation of the developed tool on large scale systems Deliverable related to Task 42

Report of the IPM system investigated on the down-scale test rig

Document reporting the results of the sensitivity analysis performed on the down scale turbine model with the IPM system on different parameters The relative decrease of the pressure pulsations in the draft tube with the IPM system versus no IPM system will be a key parameter Deliverable related to Task 11
