| Title of the article | Experimental study of aerodynamic characteristics of ventilation air flow stabilizer |
| Abstract. | Problem statement. Maintenance of the estimated air consumption and reduction of heat losses during the cold period of the year in natural exhaust ventilation systems can be carried out with the help of airflow stabilizers. The aim of the study is to determine experimentally the local pressure loss at various positions of the movable member of the stabilizing device, as well as the forces arising from the action of the air flow on the movable member of the stabilizing device. Results. An experimental installation was developed to study the properties of a stabilizing device, an accuracy evaluation was performed, and a series of experiments was performed. From the processed results of the experiments, data were obtained with the help of which the dimensionless characteristics were determined: the coefficient of local resistance of the devices ? and the coefficient k, which describes the effect of aerodynamic force on the moving element of the device. Conclusions. The significance of the obtained results for the construction industry consists in the applicability of the obtained experimental results for the development of designs of airflow stabilizers of the type considered, which significantly reduces the consumption of thermal power in the cold season. |
