<p>Engines and pumps are common devices that have become important sources of power to operate machines used in everyday life. Many of these machines need complex technology for proper operation. However, some of these can be operated by using simple mechanical processes. Liquid piston fluidyne engines are such devices that are a simpler version of Stirling engines. In this work, a simple test rig using this concept has been designed. Various experiments were done to test the device, and future recommendations on improvements have been presented.</p>
