Abstract
In the work presented here, numerical simulations were carried out using computational fluid dynamics and fluid–structure interactions for three-lobe journal bearing. ANSYS Workbench® software was used for the study. The elastic deformations were also considered for the analysis. The fluid pressure forces and displacements were transferred through inbuilt transfer interface available in the software. The optimized journal bearing position was achieved using a response surface optimization technique. The methodology was validated by comparing numerical results obtained with experimental results available in the literature, and a good agreement was found. The proposed numerical method was implemented to study the pressure distribution in three-lobe journal bearing considered for study at three eccentricity ratios 0.25, 0.6 and 0.75 for various speeds ranging from 1000 to 4000 RPM. Preload factor of 0.5 was considered for the study. The results were compared with a set of experimental data obtained on a test rig developed by the authors.
