  • Investigating the Effects of Mass Transfer and Mixture Non-Ideality on Multiphase Flow Hydrodynamics Using CFD Methods 

    Irani, Mohammad؛ Bozorgmehry Boozarjomehry, Ramin؛ Pishvaie, Sayed Mahmoud Reza؛ Tavasoli, Ahmad (Iranian Institute of Research and Development in Chemical Industries (IRDCI)-ACECR, 2010-03-01)
    A numerical framework has been proposed to model the interacting effects of mixture non-ideality and mass transfer on hydrodynamics of a multiphase system using CFD methods.Mass transfer during condensation and ...

  • An Improved Model to Simulate Mud (Drilling Fluid) Dispersion through Porous Media 

    Zahedzadeh, Mohammad؛ Abbasi, Saeed؛ Dadvar, Mitra؛ Shadizadeh, Seyed Reza (Iranian Institute of Research and Development in Chemical Industries (IRDCI)-ACECR, 2010-03-01)
    An improved model of mud dispersion has been introduced in this work. The advantages of this model consist of a new analytical correlation for dispersivity by using resistivity log data and using a new aspect of ...

  • Examination of the Optimized Conditions for the Conversion of NOX Pollution in DBD Plasma Reactor 

    Yarahmadi, Rasoul؛ Mortazavi, Sayed Bagher؛ Omidkhah, Mohammad Reza؛ Asilyan, Hassan؛ Moridi, Parvin (Iranian Institute of Research and Development in Chemical Industries (IRDCI)-ACECR, 2010-03-01)
    Since NOx family, one of the most important causes of air pollution, is the primary source of acid rains, ozone layer depletion, and breathing disorders, mitigation of these pollutants is now a global concern. ...

  • Correlation and Prediction of Solubility of CO2 in Amine Aqueous Solutions 

    Goharrokhi, Mahdi؛ Taghikhani, Vahid؛ Ghotbi, Cirous؛ Safekordi, Ali Akbar؛ Najibi, Hesam (Iranian Institute of Research and Development in Chemical Industries (IRDCI)-ACECR, 2010-03-01)
    The solubility of CO2 in the primary, secondary, tertiary and sterically hindered amine aqueous solutions at various conditions was studied. In the present work, the Modified Kent-Eisenberg (M-KE), the ...

  • Determination of Crystal Growth Rate and Morphology of Barium Carbonate Crystals in a Semi-batch Crystallizer 

    Khorsand, Mohammad Reza؛ Habibian, Mahmood؛ Rohani, Navid؛ Zarei, Ali Reza (Iranian Institute of Research and Development in Chemical Industries (IRDCI)-ACECR, 2010-03-01)
    A semi-batch crystallization system is used to determine growth kinetics and morphology of barium carbonate crystals, under a constant pH value and constant temperature in the various relative supersaturations. ...

  • Modeling of Methane Hydrate Decomposition by Using Chemical Affinity 

    Varaminian, Farshad؛ Abbasi nia, Zohreh (Iranian Institute of Research and Development in Chemical Industries (IRDCI)-ACECR, 2010-03-01)
    In this work, experimental kinetics data of methane hydrate decomposition at temperatures ranging from 272.15 to 276.15 K and at pressures ranging from 10 to 30 bars were modeled by using chemical affinity. This model ...

  • An Experimental Correlation for Friction Factor in Horizontal Pipe with Trapezoidal Section Inner Longitudinal Slots for Conveying of Solids 

    Karparvarfard, Sayed Hossein؛ Farahani, Azam (Iranian Institute of Research and Development in Chemical Industries (IRDCI)-ACECR, 2010-03-01)
    In order to increase the efficiency of the conveyance of the granular solids, a new experimental set-up is designed. The test rig has longitudinal trapezoidal slots in its conveying pipes. Through experimentation, a ...
