Title of the articleResearch of the flow in channels of different forms
Abstract.Problem statement. The aim of the study was to study numerically the spatial flow of air in a straight section of the duct with the help of the Fluent software package for various channel shapes (the channel cross-section was taken in the form of a circle, ellipse, oval, rectangle). The results of numerical simulation are compared with the experimental data and calculations of other authors. Results. The main results of the study are that such forms selected channels, which have the least resistance, which will reduce the energy consumed by the ventilation system. Conclusions. The significance of the results obtained for the construction industry is that the friction coefficients of pipes of non-circular cross-section are found. The optimal shape of the channel cross section is, of course, the circle. However, the ducts of the flat-oval cross section have the closest coefficient of resistance to the data of the circle, which indicates the advisability of using such channels.
Keywords.ventilation, oval channel, numerical modeling, three-dimensional flow, coefficient of resistance.
