About HELESHAW APPARATUS
The Hele-Shaw Apparatus is an advanced fluid mechanics laboratory setup designed to visualize and study two-dimensional streamline flow patterns of fluids. It is extensively used in engineering colleges, universities, research laboratories, and technical institutes for demonstrating laminar flow behavior around various objects and through different flow channels.
The apparatus consists of two transparent parallel plates separated by a narrow gap through which fluid flows at low velocity, creating a near two-dimensional flow field. Dye injection arrangement is provided for clear visualization of streamlines, flow separation, and flow distribution around models. The setup helps students understand fluid flow concepts such as streamline formation, equipotential lines, and flow around immersed bodies.
Fabricated using high-quality transparent acrylic and corrosion-resistant components, the Hele-Shaw Apparatus ensures durability, accuracy, and easy observation of experiments. Its compact and user-friendly design makes it ideal for laboratory demonstrations and educational research applications.

Working Principle
The Hele-Shaw Apparatus works on the principle of viscous fluid flow between two closely spaced transparent plates. Due to the small gap between the plates, the fluid behaves as a two-dimensional flow system. By introducing colored dye into the flowing liquid, streamline patterns and flow behavior around obstacles can be observed and analyzed effectively.
Advanced Flow Visualization ToolEngineered for educational and research settings, the Hele-Shaw Apparatus allows for instant and clear observation of fluid fronts and interface behavior. Its transparent acrylic channel, paired with high-contrast markings, enables easy demonstration and study of laminar and transitional flow patterns using colored liquids. Designed for table-top use, this apparatus combines safety, convenience, and durability.
Robust and Safe ConstructionThe frame, crafted from powder-coated mild steel, resists corrosion and daily wear, while the acrylic channel offers excellent clarity and durability. Rounded edges enhance safety during frequent handling, and all end connections are leak-proof to prevent spills during laboratory demonstrations. This ensures a secure and long-lasting experience.
Flexible and Easy OperationWith its needle valve for precise flow regulation, manual control mode, and adjustable flow settings, the Hele-Shaw Apparatus accommodates various experimental conditions. Quick couplers and a drain valve simplify setup, testing, and cleanup, while easy disassembly facilitates routine maintenance. These features make it a reliable choice for diverse educational applications.
