Numerical simulation on thermodynamic design model for small-scaled organic rankine cycle with various working fluids

Organic Rankine cycle (ORC) is one of the solutions for recovering waste heat into useful power output. Low-grade waste heat from various sources can be converted into electricity using ORC in many different aspects. The typical ORC systems in the market often require large amount of waste heat as t...

description Organic Rankine cycle (ORC) is one of the solutions for recovering waste heat into useful power output.

Hence, this paper presents the numerical simulation of small-scaled ORC using design model developed in MATLAB to study the thermal efficiency of various working fluids in limited working conditions.
