| dc.description.abstract-translated | Wind tunnel is constructed. It is characterized by a high degree of airflow laminarization. The main constructive element of this aerodynamic tube is the laminarization module. It allows the destruction of turbulent fluxes by providing a homogeneous laminar flow. In order to evaluate the performance of the developed aerodynamic tube, a series of experimental studies was conducted in the range of air velocity of 10-50?m·s-1. To establish the laws of the distribution of flow parameters relative to the section the cross-sectional analysis method was used. It consists of forming a series of measuring planes that characterize the distribution of dynamic pressure and air flow velocity relative to the testing section. After that, the received experimental data are interpreted as three-dimensional graphic dependencies of the studied quantities. There is clearly observed a certain local area of stable values of dynamic pressure and flow velocity, after which they are sharply reduced in the direction of the walls of the section for testing. As a result of the analysis, a series of digital profiles of the distribution of dynamic pressure in the measuring planes of the testing section were obtained. Analysis of the obtained graphic dependencies allowed establishing of the uneven distribution of the dynamic pressure difference in the boundary layer zone along the inner perimeter of the test section is worth noting. Because of the side of the upper wall of the test section, the dynamic pressure difference is greater than the sidewall. This phenomenon is due to the difference in area of their blown air. Consequently, at a wall with a larger contact surface, a constant air stream experiences more loss of its kinetic energy than a wall with a smaller area. Especially this tendency is observed in the turbulent boundary layer. | en |
