The article presents the study results of air distribution in a room with a flat air jet. In particular, dynamic pressure, density and viscosity of air flow were considered. Aim of a paper is to numerically simulate these physical properties of a flat air jet in a room. A graphical representation of air jet parameters was obtained using package CFD Ansys FLUENT software. A hypothesis of applying Mendeleev-Clapeyron equation to moving air flow was considered. Flat air jets have been found to be effective in terms of velocity attenuation in indoor air distribution. The dependence of the tidal flat compressed air stream velocity on time and longitudinal current coordinate simultaneously is graphically presented. Their proper long-range allows for comfortable microclimate conditions using a minimum number of them. Convergence of experimental studies results and numerical modeling confirms adequacy of a theory of the experiment.
