| 抄録 | ガス溶解と拡散物質移動の能力を含む過渡的な3D-CFD混相流シミュレーションに基づく手法を開発し，モデルが，コネクティングロッド(CR)ベアリングのオイル供給システムにおける圧力挙動と気泡の発生を決定して，CRベアリングの供給条件は，流体組成およびCRベアリング入口での体積流量の観点から，気泡の影響を強く受けていると結論付けている． |
| 抄録（英） | This paper focusses on the supply conditions of a connecting rod bearing. Thereto, a novel simulation approach is presented, which is based on a transient 3D-CFD multiphase flow simulation including the ability of gas dissolution and diffusive mass transfer. The model determines the pressure behavior and the gas bubble development in the oil supply system of a connecting rod bearing. It allows to visualize the flow behavior and the existence of gas bubbles in order to get a detailed impression of the physical occurrences. The experimental results from Maaßen, where a big gas bubble is formed in the supply bore by gas cavitation, are confirmed and used for validation. Further the flow behavior of free air ratios is investigated. The paper concludes that the supply conditions of a connecting rod bearing are strongly influenced by the gas bubble in terms of the fluid composition and the volume flow rate at the connecting rod bearing inlet. These results serve as an important basis for the definition of more detailed boundary conditions for (thermal) hydrodynamic bearing simulations. 翻訳 |
