Propeller-wing interactions of a lift + cruise eVTOL configuration during transition
Oliver Westcott, Robert Entwistle, Swathi Krishna
The wakes of a lift + cruise aircraft's vertical lift propellers interact with the wing during the transition from hover to forward flight. This study investigates how variations i…
A Low-Fidelity Method for Aerofoil Shape Optimisation for Curvilinear Blade Kinematics
Benjamin Irwin, David Toal, Swathi Krishna
This study develops a low-fidelity framework for aerofoil shape optimisation under curvilinear blade kinematics, using a hovering cyclorotor as a representative case. Aerofoil opti…
A Surfactant Prediction Model for Rising Bubbles
Lim Chi Tung James, Ivo R. Peters, Swathi Krishna
Bubbles released from a needle show shape deformations that depend on the surfactant concentration of the surrounding liquid. We develop a model that predicts the surfactant concen…
The Role of Dynamic Stall in Aerofoil Shape Optimisation for Curvilinear Blade Kinematics
Benjamin Irwin, David Toal, Swathi Krishna
This study investigates the influence of aerofoil shape optimisation on blade aerodynamic performance under curvilinear and unsteady kinematics characteristic of vertical-axis turb…
