Radial compressors are used to compress gases. The experimental unit provides the basic experiments to get to know the operating behaviour and the important characteristic variables of radial compressors. A protective plate placed in front of the inlet of the intake pipe prevents larger objects from being sucked in or the clogging of the intake opening. The medium is sucked in axially to the drive shaft by the rotation of the impeller and flows through the impeller rotating at high speed. By means of centrifugal force, the medium is accelerated towards the outer edge and is compressed in this manner. The air flow is adjusted by a throttle valve at the end of the delivery pipe. The microprocessor-based measuring technique is well protected in the housing. The experimental unit is fitted with sensors for pressure, temperature and speed. The flow rate is determinated via differential pressure measurement on the intake nozzle.

The engine has one working cylinder and a transfer cylinder arranged side by side in open communication one with another but without any intervening valve mechanism. The power cylinder has a single acting piston connected to the crankshaft while the transfer cylinder has a double acting displacer piston and regenerator operated by an eccentric, the phasing of which can be altered in relation to the crankpin of the power cylinder. The cycle on which the engine is based consists of two isothermal processes and two constant volume processes (the latter being performed with the aid of a regenerator). The source of heat is provided from a low voltage electric element so that it may readily be controlled and measured. Output is measured by the simple dynamometer supplied. The optimum phase angle can be determined and rotation can be reversed. The heating element is located at one end of the transfer cylinder, which is made of pyrex glass, so that the element and the transfer piston can be clearly seen. A variety of experiments can be carried out and the effect on performance of the use of gases of different specific heat ratio can be established. By means of the transparent cylinder the temperature of the element may be seen to fall as heat is extracted from it when the engine starts from rest. Relatively little information exists concerning the detail design of small hot air engines and this engine was designed from first principles with the aid of a computer to determine the optimum proportions of the various working elements.
Applications:
Use of gases of different specific heat ratio
Study of Hot air engine
Effect on performance
Cyclic compression and expansion of air
Closed-cycle
Regenerative heat exchanger
Temperature differential.

The model consists of two hooke's couplings that are connected by a split intermediate shaft. The deflection angle of both joints can be set individually and read on the scales. Drive is achieved by turning a hand wheel. On the drive and power take-off sides there are further angle measuring scales made of transparent plastic with which the difference between the angles of the shafts can be determined. The table model demonstrates the transmission of angular motion to joint shafts, the related gimbal error and how this error can be rectified using hooke's couplings.
