    Isothermic Gasification Octave
    (INSTITUTO DE TECNOLOGIA, 2015) MATIAUDA, Mario; DE LEÓN BENÍTEZ, Juan B.; ARTEAGA, Luis Ernesto; FREAZA, Nora; RIVERO, Marta; YACHECEN, Carlos; Eduardo de Magalhães Braga
    Gasification is a process of thermal conversion where solid biomass (sawdust pellets) is transformed 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 reactions occurring in fluidized beds. The model simulation includes mass and energy balances and hydrodynamic studies, with assumptions such as isothermal process behavior.

    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.

    Pine Wood Drying at High Temperatures
    (INSTITUTO DE TECNOLOGIA, 2015) MATIAUDA, Mario; LEÓN BENÍTEZ, Juan B. de; FREAZA, Nora; RIVERO, Marta; MAGALHÃES, Edilson Marques
    The study proposes a mathematical model to simulate the drying of Pinus elliottii wood at high temperatures, considering heat and mass transfer phenomena. The model was experimentally validated, demonstrating the evolution of moisture content and temperature in the wood during the process. The results indicate that the model shows good agreement with experimental data, proving useful for predicting drying conditions under various scenarios.
