Zusammenfassung |
Propagation of water waves can be described for uniformly sheared
current conditions. Indeed, some mathematical simplifications remain
applicable in the study of waves whether there is no current or a
linearly sheared current. However, the widespread use of mathematical
wave theories including shear has rarely been backed by experimental
studies of such flows.
New experimental and numerical methods were both recently developed to
study wave current interactions for constant vorticity. On one hand,
the numerical code can simulate, in two dimensions, arbitrary non-linear
waves. On the other hand, the experimental methods can be used to
generate waves with various shear conditions.
Taking advantage of the simplicity of the experimental protocol and
versatility of the numerical code, comparisons between experimental and
numerical data are discussed and compared with linear theory for
validation of the methods.
