Hydrogen-bubble reynolds experiment device

Abstract

The invention provides a hydrogen-bubble reynolds experiment device. The hydrogen-bubble reynolds experiment device comprises an upstream water tank, a hydrogen-bubble generator, a test section pipe,a downstream water tank and a submersible pump; the upstream water tank is connected with the hydrogen-bubble generator, the test section pipe is in a U shape, one end of the test section pipe is connected with the hydrogen-bubble generator, the other end of the test section pipe is connected with the downstream water tank, and the submersible pump is put into the downstream water tank and connected with the upstream water tank through a pipe; a self-circulation system is composed of the upstream water tank, the downstream water tank, the submersible pump and a water inlet pipe. According to the hydrogen-bubble reynolds experiment device, hydrogen bubbles serve as tracking particles, the water-body flow state of the experiment pipe is displayed, water resources in an experiment are not polluted and can be recycled, water for the experiment can be saved, and meanwhile experimental apparatuses are not corroded.

Description

technical field [0001] The invention relates to an experimental device, in particular to a hydrogen bubble Reynolds experimental device, which belongs to the technical field of fluid mechanics experiments. Background technique [0002] In fluid mechanics, the Reynolds experiment is an important experiment to study the laminar flow and turbulent flow state of fluid motion. Traditional Reynolds experimental instruments mainly use red ink or other chemical reagents that can automatically decolorize as tracers to display the flow state of water in the experimental pipeline, but there are still shortcomings, such as the use of red ink will pollute the water in the experimental pipeline, so that Water resources cannot be recycled; using decolorizable chemical tracers, although water resources can be recycled, but the chemical reagents will affect the water quality and corrode the metal components of the experimental equipment after a long time, which is not convenient for instrume...
