Abstract
We report our numerical computation of non-symmetric progressive capillary–gravity waves on water of infinite depth. The problem considered here is a classical one and there have been lots of studies on symmetric wave solutions. However we know only a few about the existence of non-symmetric progressive waves. Numerically there are only the works of Zufiria (J Fluid Mech 180:371–385, 1987; J Fluid Mech 181:17–39, 1987; J Fluid Mech 191:341–372, 1987) for gravity waves on water of finite/infinite depth and capillary–gravity waves of finite depth. All of them are non-symmetric waves with six peaks in one wave length. We made a thorough investigation in the case of capillary–gravity waves of deep water in a different numerical method with a formulation different from that of Zufiria. Then we not only demonstrate the existence of non-symmetric waves with six peaks but also clarify the mechanism of their appearance/disappearance. Furthermore we obtained a new type of non-symmetric waves.
