Računalniška dinamika tekočin (RDT) je numerično simulacijsko orodje, s katerim proučujemo različne probleme, ki obsegajo tok tekočin, prenos toplote in mase ter kemijske reakcije. Z modeliranjem z RDT lahko optimiramo različne procesne spremenljivke, izboljšamo naše razumevanje procesa in dobimo in ...

Particle coating using fluid bed technology such as Wurster chamber is a common process in pharmaceutical technology. Coatings are used to achieve variety of functions, such as: taste masking, controlled release, increase of stability and others. Coating uniformity is one of the most important param ...

Pellet coating is commonly performed in a fluid bed coater such as a Wurster coater. Computational fluid dynamics (CFD) simulations and experimental measurements of laboratory-scale Wurster coating were performed. CFD simulations were performed in a 2D axisymmetric space using the two-fluid model. T ...

A series of various methods were applied to characterize samples of pharmaceutical pellets. Fourteen pellet types were tested to obtain the coefficient of restitution, coefficient of friction, stiffness, flowability, and distribution of size, shape, and density. An atomic force microscope was used t ...

The study's primary goal was to examine the possible use of single particle mechanical properties to estimate the compressibility behaviour of a tablet's excipients during compaction. Nanoindentation was utilised to measure individual mechanical properties (Young's modulus, nanoindentation hardness, ...

Oznake: Heckell;Walker;in-die;out-die;nanoindentation;deformation;
This study investigated deformation mechanisms of some commonly used pharmaceutical fillers, such as microcrystalline cellulose, lactose, dicalcium phosphate, isomalt and cornstarch, using a combination of the in-die and out-die method with the Heckel and Walker models. The tableting mixtures contai ...

In recent years there has been a growing interest in formulating solid dispersions, which purposes mainly include solubility enhancement, sustained drug release and taste masking. The most notable problem by these dispersions is drug-carrier (in)solubility. Here we focus on solubility parameters as ...

The main objective of this study was to develop a piezoelectric probe for measuring the impact rate of particles to enable characterization of the shape of particle number density profiles and characteristic particle impact frequencies inside the draft tube of a Wurster coating chamber. Pellets from ...
