Item Description

The conversion of pressure energy into kinetic energy in the rotor is characteristic for reaction turbines. In a reaction turbine, the static pressure of the working medium in front of the rotor is higher than behind it. In this case here, the working medium is air. The experimental unit allows to understand analogies to turbines driven by steam or water. Pressures at turbine inlet and turbine outlet are indicated on manometers. The torque is determined by force measurement on a band brake. The speed is measured with an optical speed sensor. Torque, speed and temperatures are digitally displayed. The volumetric air flow rate is read off a rotameter. The turbine is fitted with a quick-action stop valve as safety device in case of over-speed. The brake drum is aircooled. The well-structured instructional material sets out the fundamentals and provides a step-by-step guide through the experiments.
