KELMANSON, BARBARA LONSDALE] Using an integral-equation method which employs the authors' new and widely applicable technique of singularity annihilation, we investigate the eddy genesis in the benchmark problem of steady viscous flow in a lid-driven cavity, two of whose opposite edges move with different velocities. The method enables us to investigate the eddy structure in the resulting flow with confidence since the singularity annihilation method results are demonstrated to be virtually independent of the boundary discretization, so effective is the suppression of the singularity. In the event that only one of the edges moves, we provide convincing quantitative corroboration of the geometrical symmetry of the corner eddies first predicted by Moffatt (1). When two edges move with a relative speed ratio, we present an interesting study of the genesis of a variety of topologically-distinct flows, and the way in which these metamorphose as the speed ratio is altered. Some remarkable comer-eddy flow structures are presented, and a full explanation of all observed flow structures is proffered. © Oxford University Press Articles nationallicence KELMANSON MARK A. aut LONSDALE BARBARA aut The Quarterly Journal of Mechanics and Applied Mathematics Oxford University Press 49/4(1996-11), 635-655 0033-5614 49:4<635 1996 49 qjmamj https://doi.org/10.1093/qjmam/49.4.635 text/html Onlinezugriff via DOI 1 research-article jats NATIONALLICENCE 856 40 https://doi.org/10.1093/qjmam/49.4.635 text/html Onlinezugriff via DOI NATIONALLICENCE 700 1- KELMANSON MARK A. aut NATIONALLICENCE 700 1- LONSDALE BARBARA aut NATIONALLICENCE 773 0- The Quarterly Journal of Mechanics and Applied Mathematics Oxford University Press 49/4(1996-11), 635-655 0033-5614 49:4<635 1996 49 qjmamj Metadata rights reserved CC BY-NC-4.0 http://creativecommons.org/licenses/by-nc/4.0 nationallicence BK010053 XK010053 XK010000 NATIONALLICENCE NATIONALLICENCE NL-oxford
