Abstract
Numerical experiment with the use of software products, such as Ansis, Star–CD, Star-CCM+ and other, helps get the fields of distributing parameters in different environments. In case of conducting numerical simulation one of the main tasks is to select the most appropriate turbulence model. This work presents analysis of results of numerical simulation of ventilation processes in production premises with spatial heat sources located on the platforms above floor level with the use of Spalart-Allmaras (SA) and k-ε turbulence models as well as LES method. A comparison of results of full-scale experiment and numerical simulation has been performed. A turbulence model k-ε has been used in numerical investigations of heat-and mass exchange processes in the nozzle of cellular humidifier of system of processing plenum air. The analysis of results of calculation and experimental data acquired at experimental installation is shown. The condition of microclimate in the working zone of premises significantly depends on the peculiarities of heat exchange through external building structures. This work presents results of numerical simulation of heat exchange through cold floors on the ground and in case of presence of underlining in the production premises with sources of heat emissions with the use of k-ε turbulence model.
