Modeling and the energy balance analysis of a hydraulic free piston engine with monopropellant-power
This paper describes a new design of a hydraulic free piston engine for human scale power systems. The piston assembly is driven by the energy released by the decomposition of the high test hydrogen peroxide (HTP) through the catalyst. The elimination of the starter, air/fuel mixing and ignition enables a compact and reliable design. This paper uses the dynamics of the first order reaction to set up the model of hydrogen peroxide decomposition. Also the models of the catalyst bed and the gas chamber are built based on the first law of thermodynamics. The conversion ratio of the HTP is analyzed through investigating the energy transmission and consumption in the engine. The energy loss in the engine is mainly due to the wall radiation and the exhaust process. So some methods are introduced to improve the conversion and reduce the heat loss meanwhile. These methods are proved to be useful for the energy saving and efficiency improvement.
