At the Surface Technology and Tribology (STT) chair in the faculty of Engineering Technology (ET), we are currently seeking a highly motivated PhD candidate to research on the topic of fundamental understanding of electrical fluid behaviour in Elastohydrodynamic lubricated contacts.
Elastohydrodynamically lubricated contacts (EHL) exists in many machine elements. The life of many machines is limited by the life of these EHL contacts. With regards to energy efficiency about 23 % of global energy is lost due to friction. By improving contacts and reducing degradation a societal impact towards zero emission can be achieved.
Whilst film thickness and traction have been studied, the electrical behaviour of the lubricant in the contact as well as possible uses of this behaviour remain an open question. By building a fundamental understanding of the electrical behaviour, novel ways to increase service life, avoid electrical damage, use the contact as an in-situ sensor, and manipulation of the friction can become accessible. We plan to develop a physical understanding of the electrical properties of contact, fluid, and interface to implement this knowledge into application, design, and thus improvement of the lubricated contacts.
The main focus of this work will extending physical understanding of the contact and fluid behaviour.
Our aim is:
To design and perform experiments to investigate the interaction of film, rheology, and interface. Ultimately the goal is to derive the laws governing this behaviour.
The PhD candidate will plan and implement the research towards the project objectives by:
You will actively participate during the progress meetings and discussions of our research chair and project partners. We encourage our researchers to present and publish their results at international conferences and in reputed journals.
