The development of software tools for calculating the flow of liquid and gas (the so-called computational fluid dynamics (CFD)) makes it possible to calculate the characteristics of the gas flow in areas with an increasingly complex configuration. In particular, the use of CFD tools is increasingly used to determine the flow parameters in the flow parts of turbomachines, such as fans, pumps, turbines, axial and centrifugal compressors. Despite the wide possibilities of these methods, they have the disadvantage of being very time consuming when creating a new flow path of turbomachines and selecting the blade geometry due to the need for numerous intermediate calculations. From this point of view, the use of faster programs based on approximate flow models in the flow parts of turbomachines is quite justified. It is their use that allows you to choose the geometry of the flow path and blades, as close as possible to the desired aerodynamic requirements. In this paper, using the example of calculating the gas flow through the flow path of a Ts4-70 centrifugal fan, the possibilities of such a model are demonstrated.

Warehouses are part of the crucial infrastructure of the logistics process of any business. The type of products stored in the warehouse also determines the type of warehouse class. The object of research in the present work is a class A warehouse with a clear height of 10 up to 13 m, equipped with systems for maintaining the indoor air quality within a very specified temperature limit. An air conditioning system is proposed, consisting of roof air conditioners (Rooftop vent), that allow maintaining the microclimate in the specified limits yearly. To achieve the specific requirements, numerical modeling of air distribution in the warehouse was performed, which shows that the use of simplified, systematized methods for the technical design of air conditioners is an unreliable approach. Moreover, the analysis shows that in high warehouses, the stagnant areas that arise cannot be overcome only by rearranging the roofing machines, but also requires the use of additional impulse mixing devices.
