Ultra-high-speed elevators are affected by various factors during operation, resulting in
complex airflow disturbances and significant piston effects. To explore the aerodynamic …

To investigate the drag reduction characteristics of a flexible plate, a numerical simulation
analysis was performed on the relationships of flexibility and thickness of a flexible plate on …

Effective drag-reduction technology is important for enhancing navigation speed, extending
endurance, and enabling efficient energy usage of underwater vehicles. In this study, we …

When the ultra-high-speed elevator car-counterweight system runs opposite each other,
significant piston effects are caused, seriously affecting the elevator operation's stability. In …

The transporting of sediments across watershed systems and their placement in reservoirs
causes expensive issues for the operators of dams in many different nations throughout the …

Active surface morphing is a nonintrusive flow control technique that can delay separation in
laminar and turbulent boundary layers. Most of the experimental studies of such control …

The phenomenon of siltation represents an enormous risk for the lifespan and safety of
dams, and there are several methods for evacuating sediments, of which the hydraulic …

Hydrodynamic effect is one of the key phenomena in journal bearing lubrication. Many
