Axial Flow Turbo Machines

Product Code : SCL-CELE-14191

Overview

The Axial Turbomachine Test Apparatus is a comprehensive experimental system for studying the operating principles, energy conversion, and flow characteristics of a single-stage axial-flow turbomachine. The apparatus can be configured to operate as either a pump or a turbine by simply changing the paddle (blade) sets, enabling a complete exploration of both operating modes within one unit.

A transparent working section allows direct observation of the blade geometry, flow behavior, and cavitation phenomena. The system includes a closed water circuit with a large-capacity tank and a centrifugal pump, ensuring clean, loss-free operation.

The unit features a motor/generator that operates in all four quadrants via a frequency converter, allowing both motoring and generating modes. The braking energy generated during turbine operation is regeneratively fed back into the power grid, promoting energy-efficient operation.

For advanced flow studies, rotors and stators with different blade angles are supplied. Velocity triangles can be constructed to visualize velocity distributions at the inlet and outlet, as well as within the rotor.
Comprehensive instrumentation—including torque and speed measurement, pressure sensors, and an electromagnetic flowmeter—enables detailed performance analysis.
