Résumé

Free piston engines (FPE), usually coupled with a linear generator, are very interesting energy conversion systems. Amongst this family, Free Piston Stirling Engines (FPSE) can be distinguished from internal combustion free-piston engines. FPSE can be operated with different kinds of heat sources such as solar energy, nuclear energy, or biomass combustion. A particular configuration of FPSE using liquid pistons is known as Fluidyne. This device consists of two U-tubes. Fluidynes are technologically simple, but they usually operate at low frequency and are generally limited to low power-pumping applications, with poor efficiency (usually lower than 1%). A new configuration of a free liquid piston engine consisting of a single U-tube equipped with valves is presented. This heat engine falls in the family of Ericsson engines. A dynamic model of this Free Liquid Piston Ericsson Engine (FLPEE) was developed. The model was developed in the Matlab/Simulink computing environment, where simulations are performed in order to obtain suitable operation conditions and predict the performance of this machine. The results obtained by these simulations are encouraging, and they motivate to design and build a prototype of FLPEE. © ECOS 2021 - 34th International Conference on Efficency, Cost, Optimization, Simulation and Environmental Impact of Energy Systems.
