Flow Channel Apparatus Manufacturer,Supplier and Exporter in India

Product Code : SCL-CELE-14121

The Flow Channel Apparatus is a versatile unit for studying open channel flows and visualizing flow patterns around immersed bodies. It is an essential demonstrator for basic fluid mechanics principles.

The central component is a clear acrylic plastic open flow channel with a high depth-to-width ratio, ideal for various experiments. Flow conditions are controlled by undershoot and overshoot adjustable weirs at the inlet and exit, which regulate flow depth and velocity. Water is conditioned via a stilling tank and nozzle to ensure clean flow with minimum disturbance.

The flow rate is measured volumetrically using the measuring tank of the hydraulic bench. A dedicated dye injection system (dye reservoir and multiple needles) is supplied for streamline pattern visualization. The apparatus also includes various models, such as weirs and drag bodies (aerofoils, cylinders, ship model), to facilitate a comprehensive range of experiments.
