Study and Selection of Working Fluids for Organic Rankine Cycle (ORC) Using Engine Waste Heat Energy

Article Preview

Abstract:

In this paper, a basic ORC system is proposed to recover the exhaust gas energy of vehicle engines, and the mathematical model of the ORC system is built. Thirteen working fluids are analyzed. The main criterion for selecting working fluids is the mass flow rate and the heat absorption rate under the same power output of single-screw expander. Then, the paper presents an analysis of the irreversibility rate and thermal efficiency of the ORC system using 4 different organic working fluids.
