Product Description
This product is a teaching experimental device used to demonstrate flow fields. According to the principle of similarity, many flow processes that occur in air can also be demonstrated through experiments conducted in water.
The main structure of this device is a small self-circulating water channel. It can be used not only to demonstrate laminar and turbulent flow processes of matching models in the water channel, but also allows users to customize other irregular resistance bodies to demonstrate phenomena such as laminar flow, turbulent flow, and flow around objects when fluid passes through resistance bodies.
The experimental device is equipped with an ultra-quiet variable-speed water pump, which allows precise adjustment of the flow velocity. The flow-straightening mechanism of the device provides a stable flow field with low turbulence during the experiment. According to user requirements, the pulse power supply can be adjusted to control the density of hydrogen bubbles generated.
