Waste heat recovery (WHR) in exhaust gas flow of automotive engines has proved to be a
useful path to increase the overall efficiency of internal combustion engines (ICE). Recovery potentials
of up to 7% are shown in several works in the literature. However, most of them are theoretical
estimations. Some present results from prototypes fed by steady flows generated in an auxiliary gas
tank and not with actual engine exhaust gases. This paper deals with the modeling and experimental
validation of an organic Rankine cycle (ORC) with a swash-plate expander integrated in a 2 L
turbocharged petrol engine using ethanol as working fluid. A global simulation model of the ORC
was developed with a maximum difference of 5%, validated with experimental results. Considering
the swash-plate as the main limiting factor, an additional specific submodel was implemented to
model the physical phenomena in this element. This model allows simulating the fluid dynamic
behavior of the swash-plate expander using a 0D model (Amesim). Differences up to 10.5% between
tests and model results were found.
