DOI: 10.1017/jfm.2019.1002
Abstract: The dynamics and control of a vortex pair in ground effect are investigated in a planar, incompressible and laminar setting. The evolution of the vortices obtained numerically shows vortex rebound as a consequence of the… read more here.

DOI: 10.1017/jfm.2020.263
Abstract: In this paper, we investigate the impingement of a two-dimensional (2-D) vortex pair translating downwards onto a horizontal wall with a wavy surface. A principal purpose is to compare the vortex dynamics with the complementary… read more here.

DOI: 10.1017/jfm.2020.803
Abstract: Abstract The shapes of two steadily rotating, equal circulation, two-dimensional hollow vortices are determined and their properties examined. By means of a numerical scheme that accounts for the doubly connected nature of the fluid domain,… read more here.
