Weakly non-linear free oscillations in a basin of variable depth     

A. V. Konovalov  Yu. V. Manilyuk  L. V. Cherkesov 《Physical Oceanography》1992,3(2):87-94

Weakly non-linear free oscillations in a basin of variable depth filled with non-viscous fluid are investigated in terms of the long waves theory using the perturbation technique. Solutions to the initial two approximations for the horizontal velocity component and free surface departure are numerically derived. An attempt is made to determine the area of applicability of the linear theory by applying a parabolic bottom profile to the basin.Translated by V. Puchkin.  相似文献   

The influence of the gulf’s geometry on seiche oscillations in an enclosed basin     

Yu. V. Manilyuk  L. V. Cherkesov 《Physical Oceanography》1997,8(4):217-227

The finite-elements technique is applied to study the effect of a basin’s geometry (bays, harbours) and location of the characteristics of seiche oscillations in the basin and in the gulf proper. An increase of the length of the bay is shown to contribute to the periods of natural oscillations and to cause their restructuring. Translated by Vladimir A. Puchkin.  相似文献

A mathematical model based on the finite element technique is applied to study seiche oscillations in the Sea of Azov in an approximation of the linear theory for long waves. The model has been used to compute periods of the initial ten seiche modes.Translated by Vladimir A. Puchkin.  相似文献

Weakly non-linear waves forced by atmospheric disturbances in a confined basin of variable depth     

A. V. Konovalov  Yu. V. Manilyuk  L. V. Cherkesov 《Physical Oceanography》1992,3(6):409-416

Forced weakly non-linear oscillations of a homogeneous non-viscous fluid in a confined basin of variable depth are considered in a long-wave approximation. Fluid oscillations are caused by time-periodic fluctuations of the atmospheric pressure, whose spatial distribution corresponds to the first mode of free linear waves.Translated by V.

The generation of barotropic waves in a confined three-dimensional basin by periodic, spatiallydistributed atmospheric pressure perturbations is considered in terms of linear theory. The analytical solution for a rectangular basin is compared with the numerical one.Translated by Vladimir A. Puchkin.  相似文献
