Abstract:
Methods of laboratory modeling of 2D water flows in a rectangular channel are developed. The flow is produced in a vertical tube of a rectangular cross section when water flows through the hole in the bottom of the tube. In the setup, a short-term (up to $\sim$ 15 s) laminar water flow with a velocity up to about 18 cm/s is produced. The methods for recording the flow velocity and the type of the flow past models of various shapes are developed.
