Name | Ph.D. Position @ Soete Laboratory - Active Control of Lubricant Temperature in Rolling Element Bearings |
Company | UGent - fea |
Description | Context – High performant and power-dense electromechanical systems (e.g. weaving looms, compressors, gearboxes, drivetrains, …) need oil lubrication to reduce friction and resulting in wear in the contact between two surfaces and to efficiently dissipate heat from the lubrication points. These systems consist of multiple oil-lubricated bearings of various types, which typically operate under different and/or varying conditions (load, speed, temperature). Ideally, the lubrication properties have been adapted to these operating conditions. However, in practice in most machinery, a single uncontrolled lubricant circuit is used with multiple oil-lubricated bearings, compromising the optimal lubrication properties. As such, each individual bearing operates under suboptimal lubrication conditions, leading globally to an increased Total Cost of Ownership (TCO) due to reduced energy efficiency, reduced component lifetime, and increased maintenance and downtime. Your job – The envisioned Ph.D. focuses on the development of an accurate and reliable transient 3D Thermo-Elastohydrodynamic lubrication model, involving precise constitutive modeling of relevant thermomechanical properties, for rolling-sliding contacts and builds upon existing CFD-FSI models constructed in the opensource software OpenFOAM. After validation of experimental results, the model will be used to analyze the influence of (active) temperature control on TEHL under dynamic operating conditions, and a thorough assessment of the effectivity of the proposed concepts at the contact level will be made. As the contact model is part of a larger multi-scale approach, meta-models will be created serving as input to large-scale bearing calculations.
