The Organic Rankine Cycle is showing promising results for waste heat recovery on long haul truck applications. This technology could further increase the efficiency of current truck powertrains. In such a context, the dynamic simulation of a Rankine cycle is found to be very important to study its starting and shutting down phases, control strategies and their limits. Such studies are not always easy to perform on a test bench. This paper deals with the dynamic simulation of a Rankine cycle done under a one dimension commercial fluid dynamic simulation tool (GT-Power). After a brief summary of the component modelling, the paper focuses on the starting and initialization of the model as well as the strategies applied to make the simulation converge. Tank sizing and temperature limitations are addressed to illustrate the use of the model. [less ▲]
