Slavica Ristiĉ Jovan Isakoviĉ Biljana Iliĉ Goran Ocokoljiĉ
Testing flow quality in wind tunnels, a highly significant activity in the field of experimental aerodynamics, includes a range of different methods and application of modern equipment. In this paper, the review of the most significant methods for subsonic and supersonic flow velocity measurement in the test sections of the wind tunnels is given. Apart from the basic principles and corresponding equipment, each method is illustrated by the results available in the references or obtained in the VTI aerodynamic laboratories.
Key words: experimental aerodynamics, flow velocity, velocity measurement, pressure measurement, measuring methods, wind tunnel.
