A Hele-Shaw cell (Hele-Shaw flow – Wikipedia) is an apparatus with two parallel transparent walls with a very small gap between them filled with a very viscous. ) that Hele-Shaw cells can be used as an apparatus for visualizing the streamline pattern of two-dimensional Euler flows of an ideal fluid past an obstacle. ∇(p + ρgy), y vertically upwards for flow of a liquid of viscosity µ through rock of permeability K. When ∇ · u = 0 we again have ∇. 2 p = 0 and vertical Hele-Shaw .

Science Laboratory Equipment in Bengaluru. The equipment consists of a channel formed between two plates.
Hele Shaw Apparatus
The proper usage of the facilities help in qualitative and quantitative production of offered range within predetermined time frame. The apparatus can represent water seepage appwratus solids, and can simulate any process satisfying the Laplace equation in two dimensions.
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. Call Send a quick message. Product Description Hele-Shaw apparatus produces streamline sin a laminar, steady flow.
The apparatus comes with a rubber sheet from which to cut hsle various shapes of models.
Also, valves and a vacuum pump allow students to connect two sources and two sinks or any combination of both. Water flows along the channel at a low Reynolds number, so the inertia forces are not important. Hele-Shaw flow is defined as Stokes flow between two parallel flat plates separated by an infinitesimally small gap, named after Henry Selby Hele-Shaw appxratus, who studied the problem in These are manufactured by our competent professionals, using premium grade quality raw materials that are procured from renowned and reliable vendors of the industry.
This equation apparatux supplemented by the no-penetration boundary conditions on the side walls of the geometry. The removable top glass apoaratus has grid lines to help analysis of the flow patterns. When the gap between plates is asymptotically small. The apparatus comes with a rubber sheet from which to cutout various shapes of models. Hele-Shaw apparatus produces streamline sin a laminar, steady flow.
Thus lecturers can also use itto The governing equation of Hele-Shaw flows is identical to apparaatus of the inviscid potential flow and to the flow of fluid through a porous medium Darcy’s law.
The apparatus works with a steady, air-free water supply and suitable drain. The removable top glass plate has grid-lines to help analysis of the flow patterns.
Year of Establishment The apparatus can represent water seepage through solids,and can simulate any process satisfying the Laplace equation in two dimensions. Approximation to Hele-Shaw flow is specifically important to micro-flows.
Add to My Quote. It allows students to study various source and sink arrangements, and look at flow around an unlimited variety of different shaped models.
Hele Shaw Apparatus – Manufacturer, Exporter & Supplier
A dye flowing through several small holes at the upstream end produces streamlines. When placed between the two plates, students can see the streamline patterns flowing around the models.

Laboratory Instruments in Bengaluru. To perform experiments, students start the water flow and open a dye valve just enough to produce easily visible streamlines.
Views Read Edit View history. For such flows the boundary conditions are defined by pressures and surface tensions. The apparatus can represent water seepage through solids, and can simulate any process satisfying the Laplace equation in two dimensions. Thus lecturers can also use itto represent flow in other branches of engineering, such as aerodynamics or electricity and heat flow.
