The invented colouring device includes container, soft tube and inserter.

Description

1. Technical field [0001] The invention relates to a simulation demonstration method used in teaching and scientific research, specifically a two-dimensional simulation demonstration method of fluid phenomena, and also relates to a special dyeing device for realizing the method. 2. Background technology [0002] The nonlinear behavior of various fluids such as vortex street and turbulence is a very common phenomenon in nature, and it is also one of the objects of natural science research. It is often necessary to demonstrate its changes intuitively in teaching and scientific research. The existing simulation demonstration process is to first form a flowing liquid film on the simulation demonstration device, and then observe the fluid phenomenon through the following demonstration methods: [0003] (1) Diffuse reflection method [0004] The diffuse reflection screen under strong white light is used as the light source to irradiate the liquid film, and the interference fringe...
