| Abstract: | The approximate monochromatic progressive surface wave is generated by a piston wave maker, the vortex pair which ascends steadily is generated by a splint vortex maker in a two dimensional cistern. On the condition of Froude number being 0.5 approximately, we obtain the deformation of wave patterns produced by interaction of the vortex pair with the progressive surface waves which have different wave length and amplitute; our experimental results confirm the related theoretical research and numberical simulations. The present study provides an experimental method for the further analysis of interaction between a pair of counter rotating vortices and a progressive surface wave. |
