Abstract: Planetary gear trains (PGTs) are used in automatic transmission to achieve any desired speed ratios. At present, the study on the relationship between speed ratio and topology is not significant. Therefore, this paper ...

Abstract: Cavitation erosion in hydraulic machinery constitutes a multifaceted, instantaneous physicochemical process resulting in material wear and decreased efficiency. This paper employs an enhanced Eulerian–Lagrangian method to ...

Abstract: A modified partially averaged Navier–Stokes model (MPANS) is proposed by treating the standard k–ε model as the parent model and formulating the unresolved-to-total kinetic energy ratio fk as a function of the local grid ...

Abstract: In this experiment, it was the first time that the center oil film thickness between W-N helical gear tooth profiles has been measured indirectly through measuring the change of gaps of a ...

Abstract: To simulate the microscale bubble distribution and its effect on high-frequency cavitation noise, we present a two-way transition and coupling Euler–Lagrange model. The model accounts for both cavity fission and environmental ...
