Analysis of Eulerian Methods for Droplet Collection Efficiency on Two-Dimensional Surfaces Under Aircraft Icing Conditions

The calculation of droplet collection efficiency is a critical procedure in numerical simulations of aircraft ice accretion and anti-/de-icing processes, in which the Eulerian framework is predominantly employed, especially on complex surfaces. Based on the droplet streamlines ob...

Al-Ti intermetallic formation by cold spraying and friction stir processing

This study proposes a method for the formation of Al-Ti intermetallic compounds. A dense Al/Ti alloy composite deposit with a porosity of less than 1% was first prepared by cold spraying. Friction stir processing was subsequently utilized to enhance interfacial diffusion and prom...

Flutter characteristics of a two-dimensional prepositive elliptical wing–main wing combined configuration

Flutter is a complex dynamic aeroelastic problem that poses a significant threat to flight safety, making its mitigation a critical focus of aeronautical research. This study proposes a two-dimensional prepositive elliptical wing–main wing combined configuration (abbreviated as p...

Research on Mechanism of Fatigue Life Enhancement in Ball Bearings by Residual Compressive Stress

While the beneficial effect of residual compressive stress (RCS) on rolling bearing fatigue life is empirically well-established, the underlying mechanisms, particularly its influence on the subsurface stress field responsible for fatigue initiation, remain inadequately explored....
