An experimental free displacer back-to-back gamma type Stirling engine
Abstract
A novel type of Stirling engine has been designed and is currently at an advanced manufacturing stage at the School of Mechanical Engineering at the University of the Witwatersrand. The engine offers the main advantage of eliminating many of the sealing problems usually associated with Stirling engines and in one of its final configurations, it consists of only two moving parts. This follows previous work on a rig that has been used for low speed testing of the concept (up to 3,5 Hz) and at temperatures of up to 573 K. The engine has been designed on a modular basis to enable full experimentation. The displacer block that includes the heaters, regenerators and coolers is located on top of a modified Petter compression ignition engine which is used to provide the volume variations.
