Potential Flow Demonstrator Manufacturer,Supplier and Exporter in India

Product Code : SCL-CELE-14115

This apparatus, the Tesca Potential Flow Demonstrator, is an experimental unit used to study two-dimensional, inviscid potential flow, which serves as an excellent approximation for the flow of ideal fluids. The core element is a Hele-Shaw cell, which creates laminar flow by having water move at a low velocity through a narrow, 5 mm gap between two parallel glass plates. This parallel flow is irrotational and non-viscous, making it suitable for demonstrating potential flow concepts.

The principle is based on the Laplace equation, allowing the demonstration of analogies between potential flow and other physical systems like current flow, heat flow, and magnetic flux. Streamlines are made visible by injecting a contrast medium (ink) into the water.
