Item GESTÃO TERMOECOLÓGICA DE USINAS TERMOELÉTRICAS COM MOTORES DE COMBUSTÃO INTERNA: MODELO BASEADO EM ASPECTOS TÉCNICOS, ECONÔMICOS E AMBIENTAIS(Universidade Federal de Santa Catarina, 2017) SILVA, Wagner Ferreira; CAMPOS, Lucila Maria de SouzaAlthough there is a global trend toward renewable energy use, in thermoelectric plants, the main energy source remains fossil fuels. These plants, while generating the required electrical power for consumption, are significant sources of environmental pollution. This thesis develops a proposal for the thermoecological management of thermoelectric plants, jointly evaluating the thermal and environmental efficiency of internal combustion engines powered by fossil fuels, specifically fuel oil and natural gas. Different mathematical models were created and used in the development of procedures integrating technical (efficiencies), economic (fuel consumption and cost), and environmental (emission index, ecological function, and eco-efficiency) aspects. For the first time, the concept of entransy is applied to evaluate engine efficiency and to enhance the ecological function initially developed by Angulo-Brown. The concept of eco-efficiency was employed in the multi-objective optimization of load dispatch, allowing managers to evaluate different simulations in pursuit of higher thermoecological efficiency. Practical evaluation was carried out through the application of these procedures in a specific software for the type of thermoelectric plants analyzed. The main results include theoretical advances in thermoecological management and the creation of a practical tool for data analysis and decision-making. The effectiveness of the proposed procedures was demonstrated in real cases with different generation and fuel type scenarios.Item Tube and Shell heat exchanger optimization taking into account Mechanical restrictionsv(INSTITUTO DE TECNOLOGIA, 2015) RODRÍGUEZ, Maida Bárbara Reyes; RODRÍGUEZ, Jorge L. Moya; FONTICIELLA, Oscar Cruz; DONÉSTEVEZ, Eduardo Migeu Fírvida; Prof Dr. Davi do Socorro Barros BrasilThe study introduces a multi-objective optimization procedure for shell-and-tube heat exchangers, incorporating thermal, hydraulic, and mechanical constraints to ensure equipment durability. Implemented in MATLAB using genetic algorithms (NSGA-II), the method optimizes design variables while adhering to mechanical standards. Results validate the approach against literature examples, highlighting cost and performance improvements.
