Plasma flow control of the tip vortices over a very low aspect-ratio wing (2022)
Journal Article

Flow control of the tip vortices over a very low aspect-ratio wing was carried out using the dielectric-barrier-discharge plasma actuators. The results indicate a large change in the aerodynamic forces by plasma flow control, where the lift coefficie...

Development and interaction of vortices over a very low aspect-ratio wing under pitch-up motion (2022)
Journal Article

The vortical structures over a thin rectangular wing with a very low aspect ratio of 0.277 were investigated in a wind tunnel at an effective Reynolds number of 3×106. When applying pitch-up motion pivoted at mid-chord, the maximum lift angle was inc... Read More about Development and interaction of vortices over a very low aspect-ratio wing under pitch-up motion.

Opposition control of turbulent spots (2022)
Journal Article

Opposition control of artificially initiated turbulent spots in a laminar boundary layer was carried out in a low-turbulence wind tunnel with the aim to delay transition to turbulence by modifying the turbulent structure within the turbulent spots. T... Read More about Opposition control of turbulent spots.

Hydrophobically/oleophilically guarded powder metallurgical structures and liquid impregnation for ice mitigation (2022)
Journal Article

Icing hazards often pose operational and safety challenges. Various surface and coating approaches have been attempted for ice mitigation purposes, but the durability remains an outstanding issue. Inspired by traditional powder metallurgy and slipper... Read More about Hydrophobically/oleophilically guarded powder metallurgical structures and liquid impregnation for ice mitigation.

A phase-field method for three-phase flows with icing (2022)
Journal Article

A numerical scheme to simulate three-phase fluid flows with phase change is proposed. By combining the Cahn-Hilliard model for water-air interface, Allen-Cahn equation for ice and fluid and Navier-Stokes equation for momentum, we solve the evolution...
