The FLEXTURBINE consortium is built around an industrially initiated nucleus: Core representatives of the European turbine industry have joined forces and involved leading European universities and research institutes to address the identified research and technology questions. They will cooperate to achieve the project objectives, sharing experience and know-how and developing results with complementary skills. The following figure outlines the contributions of each partner to the FLEXTURBINE topics and the impact on the future market drivers for flexible energy generation.
The consortium setup comprises all steps of the value chain and thus ensures that the technology is applied as soon as possible. The industrial design capabilities are complemented by selected high profile university departments, which are also involved in modelling activities as well as in preforming rig and component tests.

Consortium Map & Partner Details

Lulea University of Technology

Luleå University of Technology (LTU) is one of the major Swedish universities 

focussing on applied research in close collaboration with industry. The Division of Machine Elements at LTU has been engaged in tribology research for the past four decades and, today, is acknowledged as one of the world’s leading tribology research groups. The activities on modelling of lubrication in all regimes are world-leading and have attracted three international prizes (best paper awards) during 2010-2014. The division has attracted large research funding from national agencies and has played a leading role in various national and European programmes such as Swedish Resarch Council (VR), COST, and Marie Curie Actions. The Division has established the state of art laboratory known as “Tribolab” one of Europe’s best equipped tribo-test labs. The Division has long tradition to work with industry in order to help them to find innovative solu-tions to their tribological and lubrication problems

Role in the project

LTU will be responsible for modelling and simulation of bearing performance, with a special focus on dy-namic loading, 

stability, and power losses. LTU will also investigate how lubricant rheological parameters influence the bearing performance. LTU will further develop models and theories for lubricated contacts and learn more about bearing opera-tion under extreme conditions. Furthermore, LTU will train at least one PhD-student to become an expert in the field and later be employed in turbomachinery industry.

LTU will develop new bearing analysis software, which can take the following effects into account: non-steady bearing operation, non-Newtonian lubricants, thermal effects, surface roughness effects, and bearing deformation. LTU will therefore contribute to more robust bearing designs with lower power loss, less risk for instability and more resistant to failures.

 

Personnel involved

Prof. Roland Larsson

Professor of Machine Elements. Expert on journal bearing lubrication and especially bearing modelling and simulation. 

The career started at ABB Stal, Finspong, Sweden 1988. He was then trained to become bearing and rotordynamics expert. Later he joined Lulea University of Technology and defended his PhD-thesis in 1996. The PhD-work as well as his research until now has been focussed on tribology with specialisation on modelling and simulation of lubrication processes.
