INVESTIGATION OF PACKED BED CHARACTERISTICS USING SPHERICAL PARTICLES

Several semi-empirical modified equations for the pore size and porosity had been suggested depending on the parameters affecting them for sphere particles of mono, binary and ternary packing systems. The parameters affecting the pore size were found to be the particle diameter, the porosity of the bed and the permeability to fluid flow. The parameters affecting the porosity in the packed bed of sphere packing are the particle and bed diameters. Several types of packing materials with different sizes have been used in the packed bed, and each had been studied separately.

STUDY OF TUBE REDUCTION USING DIE-LESS DRAWING

A study of die-less tube sinking is carried out in which the conventional reduction die is replaced by a die-less stepped bore reduction unit (DRU). The DRU is a single cylinder of two concentric bores with different diameters, where the smallest bore diameter is slightly greater than the outer tube diameter before deformation.
