Being an energy-saving project with great development potential, Organic Rankine Cycle (ORC) is becoming one of the research hotspots in recent years. However, there is little research about the waste heat recovery with Organic Rankine Cycle on ships as yet. In this paper, the marine diesel engine waste heat recovery system with Organic Rankine Cycle was designed and analyzed. Isopentane was used as working fluid in the Organic Rankine Cycle. The conditions for the system to recover marine diesel engine waste heat were given, and its schematic diagram was provided. Finally, the ORC turbine which is the most important components of the system was designed. The numerical simulations of the ORC turbine were carried out by using the CFD program. The operation performance and flow field were analyzed.

Firstly, this paper briefly introduces the Utilization status on marine diesel engine waste heat recovery. Combined with the characteristics of waste heat caused by marine diesel engine and technology of organism Rankine cycle, the paper designs a new waste heat recovery system for marine diesel engine based on organism Rankine cycle, And through researching the changes of temperature between marine diesel engine waste heat and the system working medium, pure organism R123, R245fa or R134a are selected as system's cycle fluid because of environmentally friendly and cycle performance more appropriate. The system application of economy on the ship are analyzed in the theoretical calculation.
