  • Beneflciation Studies of Bama Oxidized Lead and Zinc Ore 

    Abdoulzadeh, A.؛ Oliazade, M. (Materials and Energy Research Center, 1997-08-01)
    Bama is one of the major concentrating plant in Iran which treats nearly 1500 tons per day sulphidic lead and zinc ore. Large amount of oxidized ore exist in Bama which has been extracted along with sulphidic ore. The main ...

  • A Numerical Study of Natural Convection and Radiation Interaction in Vertical Circular Pin 

    Soleimani, G.؛ Khoshravan-Azar, Esmaeil (Materials and Energy Research Center, 1997-08-01)
    A numerical finite difference study has been earned out for two dimensional radiation-natural convection interaction phenomena in a vertical circular pin located at a non-participating (i.e. transparent) fluid. The coupled ...

  • Shape Effects and Definition of Hydraulic Radius in Manning 's Equation in Open Channel Flow 

    Mohammadi, M. (Materials and Energy Research Center, 1997-08-01)
    In the Manning equation the hydraulic radius can be defined as the cross-section dimension of the shape. In pipe flow the bed shear stress is assumed to be uniformly distributed along the wetted perimeter which cannot be ...
