Abstract

<p>This paper attempted to estimate the values of the cavitation pressures of seal-type thrust bearings with dimples of different diameters and depths, comparing experimental and analytical results. In the experiments, the oil film forces were measured for the various dimpled bearings with a fixed oil film thickness. The measured oil film forces were simulated by CFD analysis and the mass-conserving cavitation algorithm which implemented the JFO theory, using various cavitation pressures. In addition, cavitation pressures for a dimple were measured experimentally in various rotational speeds. As the results, the estimated cavitation pressures from the JFO analysis were slightly larger than those from CFD analysis. Cavitation pressure did not change much for the different dimple diameters, while it increased as the dimple depth increased. The measured cavitation pressure was generally consistent with the estimated results by CFD analysis, and it tended to increase gradually with increasing rotational speed.</p>
