Influence of Flow-induced Vibration of a D-VAWT With and Without Leading-edge Rod at Various Pitch Angles [PDF]

Journal of Applied Fluid Mechanics
Under specific incoming wind speeds, Darrieus- Vertical Axis Wind Turbines (D-VAWT) have been found to display significant amplitude vibrations. Previous studies mainly examined the D-VAWT's aerodynamics, ignoring flow-induced vibration (FIV).

Numerical Research on the NS-SDBD Control of a Hypersonic Inlet in Off-Design Mode

Aerospace, 2022
The overall performance of a scramjet inlet will decline while entering off-design mode. Active flow control using nanosecond surface dielectric barrier discharge (NS-SDBD) can be a novel solution to such inlet–unstart problems.

Bubble clustering in turbulent boundary layer on a moving wall utilizing belt-driven system

Journal of Fluid Science and Technology
For simulating the behavior of air bubbles injected into the turbulent boundary layer developed beneath the bottom of a ship, we propose a novel experimental system for a different driving force on flow from the bulk pressure gradient.

Queue Dynamics With Window Flow Control [PDF]

, 2010
This paper develops a new model that describes the queueing process of a communication network when data sources use window flow control. The model takes into account the burstiness in sub-round-trip time (RTT) timescales and the instantaneous rate ...

Applying colour-coded particle image velocimetry to the wake of a delta wing across a wide range of angles of attack

Journal of Fluid Science and Technology
The forces acting on a delta wing are predominantly influenced by local flow structures, specifically leading-edge vortices (LEVs). This study applies colour-coded particle image velocimetry (PIV) to quantify wake dynamics and lift generation for a delta
