The article deals with experimental study of constant area mixing in subsonic axi-symmetric air ejector. Particle Image Velocimetry (PIV) and Constant Temperature Anemometry (CTA) measurements of four different mixing regimes, each with different ejection ratio were performed. For PIV measuring, the velocity fields inside the constant area mixing chamber were taken through the vitreous wall of the chamber, while the laser beam entered it from the opened outflow of the ejector. For CTA measuring, probe perpendicular to the ejector axis was used. Data obtained from both methods are compared. Basic descriptions of the results are given and it is claimed that results are reliable
