Capillary waves past a flat plate in water of finite depth
1 School of Mathematics, University of East Anglia, Norwich NR4 7TJ, UK
Free-surface flow past a semi-infinite flat plate in a channel of finite depth is considered. The fluid is assumed to be inviscid and incompressible, and the flow to be two-dimensional and irrotational. Surface tension is included in the dynamic boundary condition but the effects of gravity are neglected. It is shown that there is a three-parameter family of solutions with waves in the far field and a discontinuity in slope at the separation point. This family includes as particular cases the solutions previously computed by Osborn & Stump (2001, Phys. Fluids, 13, 616623) and by Andersson & Vanden-Broeck (1996, Proc. R. Soc., 452, 19851997).
Keywords: free surface flows; surface tension; water waves.
