Comparison of Hydrodynamic and Elastohydrodynamic simulation applied to Journal Bearings 2010-36-0360
Due to the huge demand for more efficient engines, as consequence of reduced pollutant emission, not only has the automotive industry been trying to achieve deeper understanding of the physical mechanisms present in the engines, but also to improve its mathematical modeling. Concerning the journal bearings, this task has extreme relevance, when either downsizing or repowering approaches are aimed to be performed. Regarding the mathematical models, identification of a model which is able to guarantee both reliable results and non-prohibitive computational costs should be achieved. This work aims to present the comparison between hydrodynamic and elastohydrodynamic simulation, showing the particularities of each approach and its advantages and disadvantages.
