Bachelor’s/Master’s thesis: Computational Fluid Dynamics (CFD)-based investigation of hydraulic losses in roller bearings

The Institute for Machine Elements and System Development researches the fundamental structural and tribological behaviour of machine elements and maps this in experimentally validated model descriptions. These model descriptions are used to analyse and design the functional, loss and noise behaviour of entire technical systems with a focus on drive technology. The models developed are also used to research and develop methods of model-based systems engineering as a central element of future industrial product development processes.

Hydraulic losses caused by displacement and shearing of the lubricant on the components of a rolling bearing have a significant but not yet sufficiently researched influence on kinematics. As part of the thesis, a computational fluid dynamics (CFD) model of a cylindrical roller bearing is to be constructed, and the influences of different operating conditions and different operating conditions are then to be investigated. The focus is on evaluating the interaction between the fluid and the individual components.

Tasks:

• Mesh creation based on CAD files for simulation in Simerics
• Convergence and mesh study
• Simulation of various operating conditions
• Evaluation and classification of results

Requirements:

• Independent, reliable working style
• Interest in numerical flow simulation
• Prior knowledge of CFD, Simerics, Ansys, OpenFOAM, C++ or CAD is an advantage, but not essential

We offer:

• Flexible organisation of work priorities
• Fast processing options
• Intensive support
• Immediate start or by arrangement
• Very good working atmosphere
