Abstract:	In the present paper, the development of a high-resolution PIV-PLIF combined system for the simultaneous measurements of velocity and passive scalar concentration fields is described. The high-resolution PIV-PLIF combined system is used to perform the simultaneous whole-field measurements of velocity and concentration in the near field of a turbulent jet mixing flow. The characteristics of the mass transfer process and momentum transfer process in the near field of the jet mixing flows are discussed in the terms of ensemble-averaged velocity and concentration, turbulent intensity, concentration standard deviation and the correlation terms between the fluctuating velocities and concentration.
