Abstract

Non-stationary dynamics and structure of stratified and homogeneous fluid flows around a plate and a wedge were studied on basis of the fundamental equations set using methods of laboratory and numerical modeling. Fields of various physical variables and their gradients were visualized in a wide range of the problem parameters. Eigen temporal and spatial scales of large (vortices, internal waves, wake) and fine flow components were defined. The same system of equations and numerical algorithm were used for the whole range of the parameters under consideration. The computation results are in a good agreement with the data of laboratory experiments.
