Fatigue and heat transfer

seven people, limousine, marie curie actions

This work package focuses on the fluid-structure interaction during limit cycle oscillation. Two types of interaction occur: vibration coupling between fluid and structure, and subsequently an enhanced heat transfer from fluid to structure. This leads to failure due to fatigue and creep. Both the vibration amplitude and the temperature determine the time to failure. The key output of this work package is am estimate of the time to failure as a function of limit cycle amplitude, frequency and heat load. The methods used will be mainly FEM, in combination with CFD codes.

The research plan requires expertise in various fields within science and engineering, and this will be provided by an ensemble of partners with complementary knowledge and skills. Central positions will be taken by KU and UT to cover the two cores of the scientific project. One core, to be treated at KU, is the analytical investigation of nonlinear acoustic oscillations and structural vibration. The other core, to be treated at UT, is the numerical and experimental approach to these phenomena, and to combustion. More specialized contributions will be made by the other partners, who will take on well-defined tasks, matching their unique expertise. Most of these partners have participated in related EU-funded projects (see table 3) so LIMOUSINE will benefit directly from the know-how and experimental facilities acquired in these earlier projects.

Each task represents a topic for a PhD or post-doc project
