Designing of storage facilities is an interdisciplinary process that requires consideration of technical, economic, social or environmental issues. Storage facilities, as a part of supply chain are designed to provide customers availability of goods at a certain time, quantity and place. This involves the functions resulting therefrom, such as storage, sorting, picking, packing, etc. The efficiency of processes in the supply chains is strongly influenced by the location and shape of the storage facilities that are critical components. These issues are multi-threaded, and they are subject of an iterative approach in which information tools are playing a special role. One of such tool is the SIMMAG3D system. It is a system for modelling and visualization in 3D of warehouse facilities, which was built based on developed mathematical models, computational algorithms and functional dependencies necessary for the designing of storage facilities. It also takes into account the different types of warehouses and design methodologies as well as the location of warehouses in the logistic network. The article presents the elements of the SIMMAG3D system and characterizes its functional capabilities. It has been pointed out that one of the key elements of the system is the module for 3D visualization of storage facilities. In addition, an example of the visualizer operation on real data concerning one of the FMCG storage facility is provided.

A scope of the-paper was to simulate numerically gas flow in the impinging stream emulsifier. The analysis of pressure and velocity fields allowed one to determine an influence of the distance between atomizers on the droplet size in emulsions.

Results of the investigation on the effect of distance L between atomizers on mean droplet diameter in the inner phase of emulsions obtained by the impinging jet method are discussed in the paper. It was found that when the atomizers were far enough from each other, the diameters of droplets being formed did not depend on the distance between the atomizers. Below some critical value of L, the droplet diameter decreased with a decrease of the distance between atomizers. On the basis of the analysis of the effect of distance L between the atomizers on mean droplet diameters, the authors proposed an empirical model.

Celem badań było rozwinięcie metody otrzymywania emulsji o małych rozmiarach kropel fazy rozproszonej i wysokiej monodyspersyjności za pomocą rozpylaczy pneumatycznych. W ramach wykonanych prac określano wpływ parametrów hydrodynamicznych oraz rozmiaru komory mieszania w rozpylaczu na strukturę emulsji oraz wydajność procesu. Strukturę emulsji określano wykorzystując system komputerowej analizy obrazów mikroskopowych. Mierzono średnią średnicę kropel fazy wewnętrznej oraz stopień monodyspersyjności powstających układów. Zaproponowano równanie korelacyjne pozwalające przewidzieć średnią średnicę kropel fazy rozproszonej jako funkcję parametrów procesu.

The scope of the paper was to investigate the method of obtaining emulsions using an air-atomizer. The hydrodynamics of process was investigated as well as the emulsion structure as a function of process parameters. The correlating formula was proposed for prediction of the diameter at the inner phase droplets.
