Zusammenfassung |
Formation of freak waves resulting from the wave packets propagating in
finite water depth on the background of a current is studied experimentally
and numerically. In the experiment, the freak waves appear as a result of
dispersion focusing of wave train excited by wave maker with modulated
frequency. The space evolution of the frequency modulated train is studied in
numerical simulations. We showed that in the water of finite depth, a
distance of focusing increases and amplitude in the focal point decreases in
comparison with infinite water depth. Experimental results are in good
agreement with numerical simulations if wave breaking of surface waves
does not occur. |
