Author:Atkins, M; Dala, L; Tongbeum Kim, TDate:Feb 2014The behavior of the flow around two circular cylinders arranged in a side-by-side configuration strongly depends on the transverse center-to-center gap spacing ratio (T/D) where D is the cylinder diameter. Based on the observed wake structure ...Read more
Author:Meijer, M-C; Dala, LDate:Jun 2015The basis of linear piston theory in unsteady potential flow is used in this work to develop a quantitative treatment of the validity range of piston theory. In the limit of steady flow, velocity perturbations from Donov’s series expansion ...Read more
Author:Botha, JDM; Dala, L; Schaber, SDate:Sep 2014A novel concept (referred to as the flap extension) is implemented on the leading edge of the flap of a three element high lift device. The concept is optimised using two optimisation approaches based on Genetic Algorithm optimisations. A ...Read more
