Waste Heat Recovery from Marine Diesel Engine Using Organic Rankine Cycle

Abstract

Many carbon dioxide ( ) super critical cycles and associated systems were compared in this study.

Several carbon dioxide () super critical systems were proposed, and many elements had an impact on the cycles discussed in this paper. Various working settings for super critical carbon dioxide cycles have been simulated, and diverse working has been examined. Also, a thermodynamics analysis of this system was conducted to determine the ideal operating settings for maximizing operation while increasing overall efficiency. For the analysis, the characteristic equations were solved using the MATLAB program. In addition, a performance analysis was carried out to evaluate each system's applicability and power output under various engine loads. The suggested designs also included an evaluation of their economic and environmental implications.
