Surface texture shape significantly influences the tribological and sealing properties of fluid mechanical face seals. Considering that it is a contradiction to simultaneously improve load capacity reduce leakage, numerical multi-objective optimization model proposed herein load-carrying while reducing volume leakage rate via optimization. The mass-conserving cavitating boundary condition non-dominated sorting genetic algorithm II are employed for results indicate optimal spiral-like under...
Solutions for the generation of FAIR (Findable, Accessible, Interoperable, and Reusable) data metadata in experimental tribology are currently lacking. Nonetheless, production is a promising path implementing scalable science techniques tribology, which can lead to deeper understanding phenomena that govern friction wear. Missing community-wide standards, reliance on custom workflows equipment some main challenges when it comes adopting practices. This paper, first, outlines sample framework...
The Wing-In-Ground Effect (WIG) Craft, a vehicle flying over the ground, is promising transportation mean in near future. It has high speed and low fuel consumption. current work examines performance of WIG regional 50passenger Craft designed for commercial use, by using numerical simulations. Two configurations, including airplane type Lippisch type, were taken into consideration order to achieve good capability. with rectangular wing merit making best use ground effect. reversed delta...
Surface texture modification is a reasonable strategy for improving the tribological property of friction pairs. The internal flow behavior surface significantly impacts its performance. In this study, three-dimensional computational fluid dynamics (CFD) model constructed to explore straight-groove in thrust bearing. influences Reynolds number, depth ratio, and area ratio on are systematically investigated. Furthermore, streamline performance parameters checked reveal mechanism groove...
Particle image velocimetry is applied in this study to measure the wake flow field of a Panamax Bulker ship model under ballast condition. This investigation revealed that Froude number 0.167. The time-averaged velocity, turbulent fluctuations, kinetic energy (TKE), Reynolds stresses, and vorticity information were measured perform comparison with design velocity contours indicated conditions have distinct hook-like axial contours; however, they appeared at different positions. big...
