For the purpose of evaluating optimal fill level of starting materials in a high-shear mixer, discrete element method (DEM) simulation was conducted to visualize kinetic status between particles. The simulation results obtained by changing fill levels were used to determine solid fraction of particles, particle velocity, particle velocity vector, and kinetic energy and discuss the flow pattern....

The article substantiates the need for scientific and technical developments, theoretical experimental studies of processes agglomeration powdery, viscous-plastic materials, as well materials an anisotropic structure to obtain molded bodies a given granulometry in order improve their consumer properties. A mathematical model is presented. It describes conditions material movement granulation ch...

Phase-feeding (PF) has been effective in maintaining broiler growth while reducing production cost, but the effect on different broiler strains grown in a small-bird production scenario has not been assessed. The objective of this study was to evaluate 3 commercial broiler strains typically used in a small-bird production scenario to assess the effect of various debone times and PF on yield and...

This paper investigates foam granulation in a twin screw extruder as a new continuous wet granulation technique for pharmaceutical powder drug formulations. Foamed aqueous binder has a reportedly lower soak-to-spread ratio than drop or spray liquid addition in batch granulation. This work demonstrates a twin screw extruder configuration for foam granulation and subsequently compares the new app...

Steel plates in double skin composite (DSC) panels are restrained by a concrete core and welded stud shear connectors at discrete positions. Local buckling of steel plates in DSC panels may occur in a unilateral mode between stud shear connectors when subjected to combined states of stresses. This paper studies the local and post-local buckling strength of steel plates in DSC panels under biaxi...

The mixing effect of powder materials is crucial in the iron ore granulation process, which determines composition and particle size distribution, thereby affecting quality sinter. To study particles a high speed shear mixer (HSSM) cylinder (CM), numerical simulation based on discrete element method was adopted this work. For CM, movement consists slipping slumping. HSSM, rolling cascading. int...

Using a novel biaxial confocal rheoscope, we investigate the flow of the shear induced vorticity aligned string phase [X. Cheng et al., Proc. Natl. Acad. Sci. U. S. A., 2011, 109, 63], which has a highly anisotropic microstructure. Using biaxial shear protocols we show that we have excellent control of the string phase anisotropic morphology. We choose a shear protocol that drives the system in...

In our previous studies on the granulation of juxtaglomerular cells, we were impressed with several experiments in which a kidney was perfused with blood at a high pressure and had a striking decrease in the juxtaglomerular granulation (1). Conversely, in other situations where the pressure of the blood perfusing the kidney was reduced, the juxtaglomerular granulation tended to increase (1). Th...
