Abstract
Laboratory modeling of hydrophysical processes is one of the methods for solving scientific and practical ocean research tasks. A hydrophysical water tank has been created at the St. Petersburg Branch of the P.P. Shirshov Institute of Oceanology, Russian Academy of Sciences. The work in the tank is supported by a digital model that optimizes experimental programs and methodologies. The design and technological characteristics of the water tank allow for modeling multilayer stratification. This paper describes the tank, including its geometric dimensions (7 m × 2 m × 2.2 m — length, width, depth), instrumentation and measurement system, metrological support, and the technology for creating thermal stratification. Typical profiles of two- and three-layer stratification are provided. Based on similarity theory, the permissible scales for reproducing natural hydrophysical processes are evaluated. It is shown that the created hydrophysical water tank occupies an intermediate position between salt-stratified tanks and the large thermally stratified tank at the Institute of Applied Physics, RAS. Together with the tank’s digital model, it makes it possible to reproduce hydrological conditions covering the main types of stratification in lakes, seas, and oceans, while optimizing the temporal and functional parameters of the experiments.
