Hele-Shaw flow – Wikipedia

To provide a constant head and smooth, air-free flow from your water supply, TecQuipment offers hele shaw apparatus optional Header Tank H9a. The removable top glass plate has grid-lines to help analysis of the flow patterns.

Apparatjs thus permits visualization of this kind of flow in two dimensions. Hele-Shaw flow named after Henry Selby Hele-Shaw is defined as Stokes flow between hele shaw apparatus parallel flat plates separated by an infinitesimally small gap. Retrieved from ” https: The apparatus works with a steady, air-free water supply and suitable drain.

They then use valves to allow water to flow from a source point dhaw hele shaw apparatus into a sink point, or various combinations of flow or sink points. A wall mounting header tank to provide a constant head water supply for the H9 Hele Shaw Apparatus.

The governing equation apparatux Hele-Shaw flows is identical to that of the inviscid potential flow and to the flow of fluid through a porous medium Darcy’s law. The term Hele-Shaw cell is commonly used wpparatus cases in which a hele shaw apparatus is injected into the shallow geometry from above or below the geometry, and when the fluid is bounded by another liquid or gas. A bench-mounting Hele-Shaw apparatus to demonstrate two-dimensional laminar flow around differently shaped models.

The apparatus can represent water seepage through solids, and can simulate any process satisfying the Laplace equation in hele shaw apparatus dimensions.

Views Read Edit View history. From Wikipedia, the free encyclopedia. Also, valves and a vacuum pump allow students to connect two sources and two sinks or any combination of both. By using this site, you agree to the Terms of Use and Privacy Hele shaw apparatus.

The equipment consists of a channel formed between two plates. This page was last edited on 25 Julyat This is due to manufacturing hele shaw apparatus, apparats creates shallow planar configurations, and the typically low Reynolds numbers of micro-flows.

Hele Shaw Apparatus – Manufacturer, Exporter & Supplier

Various problems in fluid mechanics can be approximated to Hele-Shaw flows and thus the research of these flows is of importance. It allows students to study various source and sink arrangements, and look at flow around an unlimited variety of different shaped hele shaw apparatus.

The equation appaatus the pressure gradient to the velocity is. To incorporate models into the free stream of the hele shaw apparatus and study the effect on streamlines, students cut the shapes they need from the rubber sheet supplied.

Various flow visualisation experiments in two dimensions, including sink and source points and flow around models, for example:. They then sandwich the model between the two plates of the apparatus and start the flow. When the gap between plates is asymptotically small.

To perform experiments, students start the water flow and open a dye valve just enough to produce easily visible streamlines. Approximation to Hele-Shaw flow is ap;aratus important to micro-flows.

HELE-SHAW APPARATUS

Thus lecturers can also use it to represent flow in other branches of engineering, such as aerodynamics or electricity and heat flow. When placed between the two plates, students can see the streamline patterns flowing around the models. Water flows along the channel appafatus a low Hele shaw apparatus number, so the inertia forces are not important. The apparatus comes with a rubber hele shaw apparatus from which to cut out various shapes of models.

For such flows the boundary conditions are defined by pressures and apparatux tensions. This equation is supplemented by the no-penetration boundary conditions on the side hele shaw apparatus of the geometry. The vacuum pump strengthens the sink points.
