Design and testing of a wireless pressure-tap anemometer for distributed wind monitoring
Background and Motivation Accurate characterization of wind loading is fundamental in wind engineering, particularly for slender and flexible structures exposed to turbulent atmospheric flows. Conventional anemometers provide accurate measurements at a specific location, but their use for distributed wind monitoring can become impractical when measurements are required at multiple points over large structures. This issue…

Aerodynamics of drone flight in complex wind farm flows (no CFD)
The use of drones in wind farms offers significant opportunities for automated inspection, measurements of the atmospheric wind, and the transport of tools and equipment. In these applications, drones may operate close to wind turbines and therefore encounter a highly complex aerodynamic environment characterized by atmospheric turbulence, wind shear, and the unsteady wakes generated by…

Wireless Sensor-Based Monitoring of Conductor Galloping
Background and Motivation Conductor galloping is a large-amplitude, low-frequency aeroelastic instability that can affect overhead transmission lines under specific combinations of wind conditions and conductor characteristics. The detection and characterization of galloping events in real-world conditions are essential for understanding the phenomenon and for developing reliable prediction and mitigation strategies. This thesis focuses on the…

Physics-based aerodynamic modeling of drone formation flight (no CFD)
The rapid growth of autonomous aerial systems is driving the development of drone swarms capable of performing cooperative missions such as environmental monitoring, infrastructure inspection, search and rescue, and parcel delivery. As these applications increasingly rely on multiple drones operating in close proximity, aerodynamic interactions between their rotor wakes become an important factor affecting flight…

Wind Tunnel Testing of Iced Conductor Bundles for Galloping Assessment
Background and Motivation Galloping is a large-amplitude, low-frequency aeroelastic instability that may develop on overhead transmission lines under specific combinations of wind conditions and ice accretion. Accurate prediction of galloping requires reliable aerodynamic data, including force coefficients and flutter derivatives, which strongly depend on the geometry of the ice accretion and the conductor bundle configuration.…

Shaping the Flow: CFD Modeling of Louvered Envelopes for High-Rise Buildings
The use of louvers as building cladding offers a promising approach to actively modify the flow around high-rise structures. Through their directional effect, they can significantly influence the local flow topology and the overall aerodynamic response of the building. The aim of this work is to numerically investigate the aerodynamic impact of a louvered envelope…

Dynamics of an aerial cableway through a time-varying meshing finite element approach
Ropeways have been used intensively for transportation of goods and people since the early nineteenth century. To study the nonlinear effects of the forces acting on the carrying cable, and how they affect the static and dynamic behaviour of the plant, a finite element model with a time-varying mesh has been developed. The system modelling…
