Development, Validation, and Performance Evaluation of An Air-Driven Free-Piston Linear Expander Numerical Model

The free piston linear expander (FPLE) is an energy conversion device that converts mechanical energy into electric energy by using a linear electric machine (LEM) without emission. This research addresses the numerical modeling of a dual-piston air-driven FPLE constructed on the basis of the free p...
