Item Isothermic Gasification Octave: Gasificação isotérmica modelada e simulada com Octave(INSTITUTO DE TECNOLOGIA, 2015) MATIAUDA, Mario; DE LEÓN BENÍTEZ, Juan B.; ARTEAGA, Luis Ernesto; FREAZA, Nora; RIVERO, Marta; YACHECEN, Carlos; Manoel Henrique Reis Nascimento, Dr.Gasification is a thermal conversion process where solid biomass (sawdust pellets) turns into gas by partial oxidation at high temperatures. The model is based on the two-phase theory (bubble-emulsion), suitable for predicting experimental results in fluidized bed reactions. It includes mass and energy balances, and hydrodynamic studies. The simulation is implemented in Octave with a graphical user interface, enabling predictions of the distribution and concentrations of gas species during the process.Item Solução de equações de balanço populacional usando a técnica da transformada de Laplace e filtros de partículas ASIR(Instituto de Pesquisas Energéticas e Nucleares, 2015) ROSA, Gabriel; MASSI, MarcosThe solution of population balance equations (PBEs) is essential for modeling processes involving the evolution of particle size distributions in multiphase systems. In this work, the Laplace transform technique was used to convert differential PBEs into algebraic equations, simplifying their resolution. In addition, the Auxiliary Sampling Importance Resampling (ASIR) particle filter method was employed to improve the estimation of particle size distributions. The proposed approach was applied to different systems, demonstrating its efficiency and accuracy in modeling complex phenomena. The results indicate that combining the Laplace transform with particle filters significantly improves the convergence and robustness of the obtained solutions.Item Elaboração de um Modelo Matemático para o Estudo do Comportamento de Efluentes Originados da Indústria do Petróleo(Universidade Federal do Pará, 2015) SOUZA, Suellyn Siqueira de; ALVES, Rui Guilherme Cavaleiro de MacedoThe objective of this work was to develop a mathematical model to predict the future behavior of treated effluents originating from the petroleum processing industry. The model was developed by dividing the effluent treatment system into subprocesses, for which submodels were developed and then integrated to form a general model. The development of the general model involved defining the input and output variables of the system, formulating general dynamic equations, acquiring process data, estimating submodels using fuzzy identification techniques, and integrating the submodels through the neurofuzzy method. The final model allowed simulations of effluent behavior under critical conditions, contributing to environmental conservation.
