In this paper, the friction characteristics of a novel Linear Joule Engine Generator operating on dry frictionmechanism is presented. A numerical model of the friction forces is represented through the development of adry friction force model integrated into a mass-spring-damper system with viscous damping and spring constantto emulate compressor and expander operating pressures. Experimental results from a Linear Joule EngineGenerator prototype are compared with the numerical simulation results predicted by the proposed frictionmodel and other reported friction models identified from the wider engineering literature. Finally, the relationshipbetween electric generator load and friction power of Linear Joule Engine Generator is established.
