Formation and Development of the Tip Leakage Vortex in a Simulated Axial Compressor with Unsteady Inflow
… between rotor blade tip leakage vortex and inflow disturbances, such as encountered in shrouded marine propulsors, was simulated in the Virginia Tech Linear Cascade Wind Tunnel equipped with a moving endwall system. Upstream of the blade row, idealized periodic inflow unsteadiness was …

High-Fidelity Modeling of eVTOL Rotor Unsteady Aerodynamic and Aeroacoustic Response to Time-Harmonic Gust
… aerodynamic and acoustic response of rotors to unsteady inflow represents a major uncertainty in community-noise assessment and certification. This thesis investigates the aerodynamic and aeroacoustic behavior of a representative eVTOL rotor subjected to time-harmonic inflow disturbances, …

Numerical Investigation of Rotor-Gust Acoustic Interactions Using the OVERFLOW CFD Solver
… is the aeroacoustic response of rotors to unsteady inflow conditions. This research addresses this gap by investigating the aerodynamic and acoustic behavior of a representative rotor subjected to time-harmonic inflow disturbances. By establishing a robust numerical framework, this thesis …

Eine numerische Methode zur Bestimmung erweiterter flugdynamischer Derivativa durch aerostrukturdynamische Simulation
… of structural vibration modes by coupling with unsteady flow processes. Determining experimentally the aeroelastic stability derivatives for complex configurations would be an extremely difficult task. In such cases, CAS may better support light weight construction optimised with respect to …
