4. 3. Optimisation of tribology of Alfa Laval separator screw gear systems

   University essay from Luleå tekniska universitet/Maskinelement

   Author : Anurag Singh; [2022]
   Keywords : Screw gears; Tribology; Wear; Lubrication; Materials; Surface; Roughness; Twin disc tribometer;

   Abstract : Gears are machine elements essential for mechanical transmission. Wear of gear teeth can causechanges in their profile geometry, causing vibration, noise, and subsequent gear failure. In this thesisproject, a twin disc tribometer has been used to mimic the actual Alfa Laval separator screw gearsystems. READ MORE

5. 4. Investigation of Variable Speed Technology when Converting Hydropower Kaplan Turbines into Fixed Propeller Turbines

   University essay from Uppsala universitet/Institutionen för fysik och astronomi

   Author : Johannes Ansved; [2022]
   Keywords : hydropower; variable speed; kaplan; turbines; model; simulation;

   Abstract : With an evolving energy system, an increased flexibility is necessary, placing additional demand on hydropower plants. New technology, in particular full size frequency converters (FSFC) and doubly fed induction machines (DFIM), allows hydropower turbines to run at different speeds than originally designed, thus making the turbine more flexible.
