Special Issue Information

Dear Colleagues,

Aerodynamics plays a vital role in many areas of modern life, from designing efficient aircraft and high-speed vehicles to developing wind turbines and improving building design. In recent years, the rapid development of experimental and numerical techniques has greatly promoted the application of aerodynamics in engineering.

The Special Issue, entitled "Aerodynamics and Its Applications," aims to provide a platform for researchers to present their most recent findings and advancements in the field of aerodynamics, as well as insights into its future developments. We welcome original research articles and comprehensive reviews that cover topics addressing, but not limited to, the following:

  • Aerospace aerodynamics;
  • Industrial aerodynamics;
  • Bio-inspired aerodynamics;
  • Computational fluid dynamics;
  • Aerodynamic design and optimization;
  • Aerodynamic measurements and experiments;
  • Wind energy utilization;
  • Intelligent aerodynamics.

Large-span suspension bridges are susceptible to wind loads. Therefore, a more precise analysis of their wind-induced vibration response is necessary to ensure the structure’s absolute safety. This investigation conducted wind tunnel tests for the construction and completion stages to reveal the vortex-induced vibration (VIV) phenomenon of a double-deck suspension bridge. The results showed that no VIV occurred during the construction stage. However, the inclusion of railings significantly deteriorated the aerodynamic performance of the suspension bridge, leading to significant VIV at +3° and +5° wind angles of attack. Additionally, reducing the railing ventilation rate can significantly suppress the VIV amplitude. A new analysis method based on computational fluid dynamics (CFD) simulation is proposed to investigate the VIV mechanism of the double-deck truss girder. Twenty-nine measurement points were used to explore the vortex that causes VIV. The numerical simulations found that the area above and aft of the upper deck dominated the vertical VIV, while the aft of the lower deck dominated the torsional VIV. Furthermore, the intensity of the vortex in these areas was significantly lower during the construction stage. Moreover, reducing the railing ventilation rate significantly suppresses the torsional VIV by reducing the intensity of the vortex in the region behind the lower deck. Full article
