Abstract
When performing various technological processes in energy, the velocity of air flows is one of the important parameters for metrological control. In addition, in the coal industry, with the deepening of mines, there is an urgent need to solve the problems of ventilation of mining, compliance with safe working conditions and, as a consequence, measuring air velocities of 0.1 m/s and higher. The national primary measurement standard of air flow in the range from 0.1 m/s to 1 m/s, created in NSC “Institute of Metrology”, provides traceability of measurements for working measuring instruments. The numerical simulation and evaluation of the aerodynamic configuration of the fairing for the national measurement standard of air flow velocity are performed in this paper. The calculations of the length of the measuring section of the inverse installation of the national measurement standard for the selected range from 0.1 m/s to 1 m/s are carried out. The purpose of the work is to investigate and improve the metrological characteristics and to provide recommendations for expanding the measurement range.
