    • Análise da fluidodinâmica de calor em leito de jorro com alimentação contínua de sólidos pela base. 

      Lima, Patrícia Moreira (Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Engenharia Química - PPGEQ, , 19/08/2004)
      The objective of this work was to develop a theoretical and experimental study of fluid dynamics and heat transfer in a spouted bed with draft tube, which operates in continuous mode with particles feed through the bottom ...

    • Secagem de sementes de gramíneas (Brachiaria brizantha) em leito fluidizado 

      Rizzi Júnior, Antonio Carlos (Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Engenharia Química - PPGEQ, , 05/12/2008)
      Drying operation is an important stage of the processing that precedes the storage of seeds, since that with low moisture contents, these can retain their power of germination and other qualities for long periods. The ...

    • Avaliação de aspectos fluidodinâmicos e da transferência de calor em leito fixo com escoamento gás-líquido concorrente vertical. 

      Moreira, Marcos Flávio Pinto (Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Engenharia Química - PPGEQ, , 02/03/2004)
      In this work, the heat transfer in packed bed with gas-liquid co-current downflow and upflow was investigated. The influence of hydrodynamic factors, of the size and shape of particles, of the length of the thermal section ...

    • Contribuições ao estudo da secagem em um leito pneumático vertical 

      Narimatsu, Cristiane Pirola (Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Engenharia Química - PPGEQ, , 30/03/2004)
      Pneumatic dryers are widely applied in industry, mainly because the transport of particulate material can be performed simultaneously with heating and drying operations. However, the design of such equipment is still based ...

    • Secagem de sólidos porosos granulares 

      Perazzini, Hugo (Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Engenharia Química - PPGEQ, , 18/07/2014)
      In the present work, an experimental study about heat and mass transfer phenomena was carried out during drying of porous media when subjected to an upward flow of heated air. The cylindrical porous media consisted of ...

    • Estudo da transferência de calor e massa no processo de secagem em leito vibro-fluidizado. 

      Oliveira Júnior, Antonio Batista de (Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Engenharia Química - PPGEQ, , 05/09/2003)
      Drying processes in fluidized and vibro-fluidized beds are nowadays being widely investigated in the literature, because such beds offer many advantages over other types of dryers. The purpose of this work is to contribute ...
