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.
The Institute of Technology at Linköping University is one of Sweden's major faculties of engineering
and science. In FLEXTURBINE, the work will be conducted by the Divisions of Engineering Materials and Solid Mechanics. The Division of Engineering Materials focuses on three main research areas, high temperature materials, mechanical behaviour of engineering materials with an emphasis on fatigue and fracture, and residual stresses. The Division of Solid Mechanics focuses on structural optimisation, deformation and fatigue life analysis in high temperature mechanics with focus on gas turbine applications (including constitutive modelling) and fatigue life in aero structural applications. The two research groups have a strong tradition of collaboration, especially in the field of fatigue of high temperature materials for turbines and engines.
LIU contribution to FLEXTURBINE will be to test and characterise the deformation and
fatigue behaviour of advanced disc and blade materials and to present ways to model the observed phenomena; an area in which LIU has long previous experience. The laboratory is well equipped for high temperature testing including rigs for creep, thermomechanical fatigue and crack propagation testing.
LIU will study the initiation and growth of short fatigue cracks under service like conditions including the effects of notches and different thermomechanical fatigue loading conditions. Furthermore, the long term effect of different surface conditions and shot peening will be studied.
Pfor Simonsson is the head of the Div. of Solid Mechanics at
Linköping University. He has extensive experience in modelling the deformation and fatigue behaviour of advanced high temperature materials, and has also been active in work regarding e.g. fiber composites and forming simulations.
Prof Moverare is the head of the Div. of Engineering Materials at Linköping University.
He has extensive experience in thermo-mechanical fatigue of high temperature materials (testing and characterization), mechanical properties and material modelling of engineering materials, effects of in-service degradation and dwell time on mechanical properties, and relationship between processing, microstructure and the mechanical properties of engineering materials.
