Abstract

In this paper, we investigated the Organic Rankine Cycle if it can be applied as an ORC-WHRS for exhaust marine engines gas. The organic fluids in the Fluid Prop library were analyzed by Cycle-Tempo program, and we chose 5 fluids that have the most ability to recover energy. Using Matlab, modified station models was analyzed from a vapor-dynamic model to simple organic Rankine cycle (suitable to wet fluids), and it showed a recovery rate of 3.0%, then a heat-recovery Rankine cycle (dry fluids) which showed a recovery rate of 3.2%. Then analyze was made for these models in order to determine the corresponded models output uncertainties with the model inputs uncertainties (the pressure, temperature and mass flow rate), where we found that there was no effect of the unreliability of the exhaust gas pressure inputs on the model's output, unlike both temperature and mass flow rate which showed that the effect of the unreliability of the model's outputs consistent with changes in its inputs.
