Model of the riverbed to study the dynamics DISTRIBUTION pollutants in aqueous medium

摘要

The invention relates to hydrodynamic structures, allowing in the laboratory to simulate the propagation of pollutants of various nature in channels investigated rivers. The object of the utility model are: - modeling of the propagation of toxic pollutants of various nature, whose use in field conditions is impossible; - determination of the temporal dynamics of the spread of contamination area; - determining the degree of dilution pollution area relative to the initial concentration at a given distance from the source; - modeling of pollutant in a given area of ​​the channel in view of its specific morphological features. The technical result that can be obtained by using a utility model, is the ability to test without involving major laboratory equipment (wind tunnels, experimental pool, etc.) allows to simplify the testing procedure to reduce labor and cost of manufacture. The task is achieved by the fact that the floor is based on laboratory tables and aligned by level. On top of the foam deck stacked modular units with the relief channel formed in a predetermined order. Relief of each channel unit is formed by burning off contours nichrome wire. Sealed docking units provides silicone sealant. construction principle ensures easy portability and design. Scale models of limited free space laboratory. A significant advantage of the model is the equality of its vertical and horizontal dimensions. This provides geometric similarity model and nature that with proper playback of flow rates and depths of flow leads to a three-dimensional image of the structure on the hydraulic flow pattern and in kind. In this case, adequately reproduced region Pollution localization. Model differs ease, mobility structure, easy to manufacture and maintain. The inventive sample illustrated by three photos.
