ABOUT GHENT UNIVERSITY
Ghent University is a world of its own. Employing more than 15.000 people, it is actively involved in education and research, management and administration, as well as technical and social service provision on a daily basis. It is one of the largest, most exciting employers in the area and offers great career opportunities.
With its 11 faculties and more than 85 departments offering state-of-the-art study programs grounded in research in a wide range of academic fields, Ghent University is a logical choice for its staff and students.

Doctoral fellow
Context – The performance of industrial gearboxes often varies due to subtle manufacturing differences, lubricant property changes, assembly inconsistencies, and fluctuating operating conditions. These variations, even in gearboxes of the highest quality, can affect durability and NVH (Noise, Vibration, and Harshness) performance unless carefully mitigated. Traditional gear design approaches, governed by standards such as DIN 3990, ISO 6336, or AGMA 2001, fall short in addressing the impact of within-tolerance surface roughness, geometric deviations, and changes in lubricant properties. As a result, these factors significantly influence contact dynamics and overall gearbox performance.
To address these challenges, Ghent University, in collaboration with Flanders-Make and KULeuven, launched the research project Rolux. This project aims to develop innovative methodologies and simulation tools for designing robust, high-performance lubricated gearboxes. A central focus of the project is creating a precise, yet computationally efficient, Thermo-Elastohydrodynamic Lubrication (TEHL) solver for rough gear contacts using advanced modelling techniques.

Positions & Tasks - As a PhD candidate, you will lead the development of a highly reliable and computationally efficient code to simulate 2D/3D Thermo-Elastohydrodynamic Lubrication (TEHL) in lubricated contacts, particularly in gear meshes. Your work will involve implementing advanced discretization schemes and numerical algorithms to solve the complex, multi-physics problems of elastic deformation, fluid flow, and heat transport, all within a reduced-order modelling framework. The dual-use solver you create will function both as a standalone tool and as a plug-in for other software, maximizing computational efficiency through Parallel C/C++ implementation and leveraging existing scientific computing libraries (e.g. PetSC) and potential GPU acceleration.
