Hele-Shaw Apparatus
Product Code : EL-FMP-11280
The apparatus works with a steady, air-free water supply and suitable drain.
The equipment consists of a channel formed between two plates.
Water flows along the channel at a low Reynolds number, so the inertia forces are not important.
A dye flowing through several small holes at the upstream end produces streamlines.
The removable top glass plate has grid-lines to help analysis of the flow patterns.
The apparatus comes with a rubber sheet from which to cut out various shapes of models.
The vacuum pump strengthens the sink points.
They then sandwich the model between the two plates of the apparatus and start the flow.
They then use valves to allow water to flow from a source point or drain into a sink point, or various combinations of flow or sink points.
