MODELING INDOOR AIR FLOWIN THE UNSTEADY MODE

The article is devoted to the decision of actual task of air distribution efficiency increasing with the help of swirl and spread air jets to provide normative parameters of air in the production apartments. It is shown that for reaching of air distribution maximal efficiency it is necessary to supply air by air jets, that intensively extinct before entering into a working area. Simulation of air flow performed with the help of CFD FLUENT (Ansys FLUENT). Сalculations of the equation by using k-εmodel of turbulence are presented.

Моделювання потоку повітря у виробничому приміщенні

Air distribution in a room by swirl and spread air jets has been regarded. Dynamic parameters of air flow that is created due to swirl and spread air jets at their leakage in a room has been determined. Jet spun at an angle of inclination jet twisting plates 90˚ similar in its characteristics to upstream. Grazing jet develops independently of swirling, ie no jets interaction. At an angle of 60˚ tilt plate twisting jet flooring jet also develops independently of swirling, ie no jets interaction.

The article is devoted to the decision of actual task of air distribution efficiency increasing with the help of swirl and spread air jets to provide normative parameters of air in the production apartments. The mathematical model of air supply with swirl and spread air jets in that type of apartments is improved. It is shown that for reaching of air distribution maximal efficiency it is necessary to supply air by air jets, that intensively extinct before entering into a working area. Simulation of air flow performed with the help of CFD FLUENT (Ansys FLUENT).
