Abstract
The need to reduce the environmental impacts generated by the consumption of fossil fuels has resulted in the intensification of the search for alternative sources of energy in the last decades. Among the most promising alternative technologies for electric power generation is the Organic Rankine cycle (ORC). ORC systems are applied to generate electricity in heliothermic and geothermal power plants, in ocean thermal energy conversion (OTEC) systems, in biomass plants and in waste heat recovery in industrial processes. This work aims to create a computational model that performs the ORC simulation for different fluids and applications. For this, mathematical models were created for different architectures of the cycle. Then these models were implemented computationally through MATLAB software. The CoolProp library was used to obtain the thermodynamic properties of the working fluids. Finally, simulations were carried out with the purpose of validating the model by comparing the data generated with those available in literature. The preliminary analyzis shows that the computational model is able to simulate the basic Organic Rankine cycle and generate satisfactory results.
